Can You Retake SCS-C02 After Failing? Retake Rules Explained (2026)

Failing the AWS Certified Security - Specialty (SCS-C02) exam doesn’t end your certification journey—it’s just a detour. If you’re reading this after seeing that dreaded “fail” result, you’re likely wondering what happens next and exactly when you can schedule your retake. The good news is that Amazon Web Services allows retakes, but there are specific rules and waiting periods you need to understand before diving back in.

Direct answer

Yes, you can retake the SCS-C02 exam after failing. Amazon Web Services has a structured retake policy that includes a mandatory waiting period between attempts, typically 14 days from your failed attempt date, though this can vary. You’ll need to pay the full exam fee again (currently $300 USD), and there’s no limit to the total number of retakes you can attempt. However, check Amazon Web Services’s official exam page for the most current retake policy as rules can change.

The key is using your waiting period strategically rather than just cramming more content. Most candidates who fail SCS-C02 struggle with specific domains—particularly Infrastructure Security (20% of the exam), Security Logging and Monitoring (18%), or Data Protection (18%). Your retake success depends on identifying exactly where you went wrong and addressing those knowledge gaps systematically.

SCS-C02 retake rules: the official policy

Amazon Web Services maintains consistent retake policies across all their certification exams, including SCS-C02. Here’s what you need to know about the official structure:

The retake policy applies immediately after you receive your fail notification. You cannot schedule your retake attempt until the waiting period expires—attempting to book earlier will simply show no available slots during the restricted timeframe. This is enforced at the system level, so there’s no workaround.

Your original exam score report provides crucial information for your retake strategy. AWS doesn’t give you your exact numerical score, but they do provide performance feedback by domain. Pay close attention to whether you scored “Below competent,” “Competent,” or “Above competent” in each of the six SCS-C02 domains:

  • Threat Detection and Incident Response (14%)
  • Security Logging and Monitoring (18%)
  • Infrastructure Security (20%)
  • Identity and Access Management (16%)
  • Data Protection (18%)
  • Management and Security Governance (14%)

This feedback is gold for your retake preparation. If you scored “Below competent” in Infrastructure Security, for example, you know that’s where 20% of your study time should focus—covering VPC security, network segmentation, AWS WAF configurations, and security group best practices.

The retake uses the same exam format: 65 questions, 170 minutes, with the same passing threshold. However, you’ll get a completely different set of questions. Don’t expect to see identical scenarios from your first attempt.

Check Amazon Web Services’s official exam page for the most current retake policy as rules can change—particularly around waiting periods and fee structures, which AWS occasionally updates.

How long do you have to wait before retaking SCS-C02?

The standard waiting period between SCS-C02 attempts is typically 14 days, but this isn’t guaranteed to be permanent. Amazon Web Services has adjusted waiting periods in the past, and different regions might have slight variations in policy implementation.

The waiting period starts from the date you took your failed exam, not from when you received results. If you took your exam on Monday and failed, your earliest retake date would typically be Monday two weeks later. However, actual scheduling availability depends on testing center capacity and your location.

Here’s the practical reality: even if the waiting period is 14 days, you might not get your preferred testing slot immediately when it becomes available. Popular testing centers in major cities often book out 2-3 weeks in advance, especially during peak certification seasons (typically Q1 and Q4 when professionals are pursuing career goals or using training budgets).

Remote proctoring through Pearson VUE can offer more flexibility, often with slots available within days of your eligibility date. However, remote testing requires a controlled environment—quiet room, stable internet, proper lighting, and no interruptions for the full 170 minutes. If your home setup isn’t reliable, waiting for an in-person slot might be worth the extra time.

The waiting period serves a purpose beyond administrative convenience. It forces a cooling-off period that prevents emotional, rushed retakes. Many candidates who fail SCS-C02 immediately want to reschedule, convinced they “just had a bad day” or “got unlucky with questions.” The mandatory waiting period gives you time to properly analyze what went wrong.

Use this time for honest self-assessment. If you scored poorly across multiple domains, you need more than 14 days of additional study. Consider whether you’re truly ready for a retake or whether you should wait longer voluntarily to ensure better preparation.

How much does a SCS-C02 retake cost?

Each SCS-C02 retake costs the full exam fee—currently $300 USD. There’s no discount for retakes, no matter how narrowly you failed your first attempt. This fee structure means a second failure costs you $600 total, and a third attempt brings your investment to $900.

The cost extends beyond just the exam fee. Consider these additional expenses:

Updated study materials: If you’re retaking more than 3-4 months after your initial attempt, you might need updated practice exams or course content to reflect any exam changes. AWS regularly updates their services, and the SCS-C02 exam evolves to include new security features and best practices.

Additional practice exams: Most candidates who failed once realize they need more realistic practice questions. Quality SCS-C02 practice exams from platforms like Certsqill typically cost $50-100 but provide invaluable insights into question patterns and knowledge gaps.

Potential time off work: If you’re taking the exam during work hours, factor in the lost income or vacation time used. The 170-minute exam plus travel/setup time typically requires half a workday.

Training courses: Some candidates invest in instructor-led training or advanced online courses between attempts, ranging from $500-2000 depending on the provider and format.

The financial pressure of retake costs actually helps many candidates prepare more thoroughly. Knowing that failure means another $300 expense motivates more serious preparation than first-time test takers who might view the initial attempt as a “practice run.”

Budget planning tip: If you’re not confident about passing your retake, consider setting aside funds for a third attempt. The psychological pressure of “this is my last affordable attempt” can negatively impact performance. Having a financial backup plan reduces test anxiety.

Some employers offer certification bonuses or reimburse exam fees, but policies vary on covering retakes. Check your company’s professional development policy before assuming they’ll cover multiple attempts.

How many times can you retake SCS-C02?

There’s no official limit to the number of times you can retake the SCS-C02 exam. Amazon Web Services allows unlimited retake attempts as long as you follow the waiting period requirements and pay the full fee each time.

However, practical limitations exist. Each retake requires the same waiting period—typically 14 days—so frequent failures quickly become time-consuming. If you’re failing repeatedly, the issue likely isn’t bad luck with questions; it’s fundamental knowledge gaps that require substantial additional study time.

Consider these milestone points:

After your second failure: Take a step back and evaluate your study approach entirely. Two failures suggest either insufficient technical knowledge or poor test-taking strategy for AWS scenario-based questions. This is when most successful candidates invest in structured training or completely overhaul their preparation method.

After your third failure: Consider whether SCS-C02 is the right certification for your current experience level. The Security Specialty is among AWS’s most challenging certifications, typically requiring 3-5 years of hands-on security experience. You might benefit from pursuing AWS Solutions Architect Associate or Security Fundamentals first to build foundational knowledge.

After four or more attempts: At this point, you’ve invested over $1200 in exam fees alone. Consider engaging a mentor, joining study groups, or pursuing instructor-led training. Some candidates benefit from switching to a different AWS certification track temporarily, then returning to SCS-C02 with broader AWS experience.

The psychological toll of multiple failures can be more limiting than the financial cost. Each failure impacts confidence and can lead to test anxiety that hurts performance on subsequent attempts. Some candidates develop “retake syndrome”—where they become so focused on passing the exam that they lose sight of actually learning the material.

Success pattern analysis shows that candidates who pass on their second or third attempt typically made significant changes to their study approach between attempts. Those who keep failing often repeat the same preparation mistakes, expecting different results.

What changes between your first and second attempt

Your retake won’t be identical to your first attempt, and understanding these differences helps you prepare more effectively.

Different questions, same knowledge domains: You’ll see completely new scenarios and questions, but they’ll still test the same six SCS-C02 domains. Don’t expect to see any repeated questions from your first attempt. AWS maintains large question banks to ensure exam security.

Your knowledge baseline: Assuming you studied between attempts, you’re starting from a higher knowledge baseline. The challenge is identifying and filling specific gaps rather than learning everything from scratch. Your score report provides the roadmap—focus intensely on domains where you scored “Below competent.”

Test-taking familiarity: You now understand AWS’s question style and the 170-minute time pressure. This familiarity is valuable, but don’t let it make you overconfident. Some retakers rush through questions thinking they recognize patterns, but miss subtle scenario differences.

Changed AWS services: If months have passed since your first attempt, AWS security services might have new features. For example, AWS Config rules, GuardDuty detectors, or IAM policy conditions could have expanded capabilities that appear in updated exam questions.

Psychological pressure: Retakers often feel more pressure than first-time test takers. You’re investing more money, time, and emotional energy. This pressure can help focus your preparation, but it can also create test anxiety if you view the retake as your “last chance.”

The most successful retakers treat their second attempt as a completely new exam rather than a repeat performance. They study with the same intensity as first-time candidates while leveraging their additional insights about the exam format and their personal knowledge gaps.

Domain-specific preparation differences: Based on your score report, your retake preparation should be heavily weighted toward your weak areas:

If you struggled with Infrastructure Security (20%), focus on VPC security groups, NACLs, AWS WAF, CloudFront security, and network segmentation scenarios. Practice hands-on labs for setting up secure network architectures.

If Security Logging and Monitoring (18%) was problematic, dive deep into CloudTrail, Config, GuardDuty, SecurityHub, and custom CloudWatch metrics. Understand log analysis scenarios and automated response patterns.

For Data Protection (18%) weaknesses, master KMS key policies, encryption at rest and

in transit, S3 bucket policies, and data classification strategies using AWS Macie.

Poor performance in Identity and Access Management (16%) requires intensive IAM policy creation, cross-account access patterns, AWS SSO configurations, and privilege escalation prevention techniques.

Strategic preparation between retake attempts

The weeks between your failed attempt and retake are critical for transforming knowledge gaps into exam success. Most candidates who pass on their second try make fundamental changes to their approach rather than just studying harder.

Start with brutal honesty about your first attempt: Review every domain score on your report. If you scored “Below competent” in three or more domains, you’re not ready for a quick retake. Consider waiting 4-6 weeks to properly address fundamental gaps. Rushing into a retake after minimal additional study typically leads to second failures and higher frustration.

Shift from passive to active learning: Reading AWS documentation and watching videos helped you understand concepts, but SCS-C02 tests application in complex scenarios. Between attempts, focus on hands-on practice. Set up actual AWS environments and configure security services. Create IAM policies from scratch. Set up GuardDuty and analyze real findings. Build VPC security groups and test network access patterns.

Practice realistic SCS-C02 scenario questions on Certsqill — with AI Tutor explanations that show exactly why each answer is right or wrong. The explanations help you understand not just the correct answer, but why the other options are wrong in that specific scenario context. This builds the critical thinking skills that separate passing candidates from those who memorize facts but struggle with application.

Address test-taking strategy weaknesses: Many SCS-C02 failures aren’t due to lack of knowledge—they’re due to poor time management or misreading complex scenarios. Practice with timed conditions. Learn to identify key scenario elements quickly: What’s the compliance requirement? What’s the existing architecture? What’s the primary constraint (cost, performance, security)?

Build scenario pattern recognition: AWS exam questions follow recognizable patterns. For Infrastructure Security questions, you’ll often see scenarios involving multi-tier applications, cross-VPC communication, or hybrid cloud connectivity. Practice identifying whether a question is asking for preventive controls (security groups, WAF rules), detective controls (CloudTrail, GuardDuty), or corrective controls (automated remediation, incident response).

For Data Protection scenarios, pattern recognition helps you quickly identify whether the question focuses on encryption key management, data classification, or compliance requirements. Each pattern has preferred AWS services and architectural approaches.

Create a retake-specific study schedule: Don’t just repeat your original study plan. Weight your time based on domain performance. If you scored “Above competent” in Management and Security Governance but “Below competent” in Infrastructure Security, spend 60% of your study time on Infrastructure Security topics rather than equal time across all domains.

Common retake mistakes that lead to second failures

Understanding why candidates fail their retakes helps you avoid repeating these patterns. The most common retake mistakes often stem from overconfidence or insufficient changes to preparation approach.

Mistake 1: Assuming familiarity equals mastery: You’ve seen the exam format and question style, but this doesn’t mean you can relax your preparation intensity. Some retakers spend less time studying because they think they “almost passed” the first time. In reality, SCS-C02 has a high passing threshold—you need solid competency across all domains, not just partial knowledge.

Mistake 2: Focusing only on failed domains while ignoring strengths: While you should emphasize weak areas, completely neglecting domains where you scored “Competent” can backfire. AWS regularly updates exam content, and your strong domains from the first attempt might include new topics on the retake. Maintain proficiency in your strong areas while intensifying focus on weak ones.

Mistake 3: Same study materials, same results: Using identical study resources between attempts often leads to identical outcomes. If your first preparation relied heavily on one course or book, diversify for your retake. Add hands-on labs, different practice exam sources, and real-world scenario practice. Each resource presents information differently and fills unique knowledge gaps.

Mistake 4: Rushing the retake timeline: The minimum 14-day waiting period doesn’t mean you should schedule your retake for day 15. Many successful retakers wait 4-6 weeks to properly address knowledge gaps. Consider your score report critically—if you failed multiple domains significantly, you need more than two weeks of additional study.

Mistake 5: Neglecting the psychological component: Test anxiety increases with each failure. Some retakers develop perfectionist tendencies, spending excessive time on individual questions and running out of time. Others become overly cautious, second-guessing correct initial instincts. Practice stress management techniques and maintain confidence in your improved preparation.

Mistake 6: Ignoring scenario complexity: SCS-C02 questions often combine multiple security domains in single scenarios. A question might involve IAM permissions, VPC security, and logging requirements simultaneously. Retakers sometimes hyperfocus on their weak domain while missing the multi-faceted nature of questions. Practice integrated scenarios that span multiple security domains.

Mistake 7: Underestimating hands-on requirements: The Security Specialty assumes extensive practical experience. You can’t pass through memorization alone. Between attempts, actually configure the services mentioned in exam scenarios. Set up cross-account IAM roles, configure VPC Flow Logs, create custom Config rules, and practice incident response procedures using actual AWS tools.

Making your retake count: advanced preparation strategies

Your retake represents a significant investment—financially and professionally. Advanced preparation strategies help ensure this investment pays off with a passing score.

Scenario-based study approach: Instead of studying services in isolation, group them by common security scenarios. Practice questions involving:

  • Multi-account security management (Organizations, SCPs, cross-account roles)
  • Incident response workflows (GuardDuty → CloudWatch → Lambda → SNS)
  • Compliance automation (Config → Systems Manager → Auto Remediation)
  • Data protection pipelines (Macie → KMS → S3 → CloudTrail)

This approach mirrors how SCS-C02 questions present integrated scenarios rather than isolated service knowledge tests.

Time-boxed practice sessions: Simulate exact exam conditions during your retake preparation. Take 65-question practice exams in exactly 170 minutes. This builds both knowledge confidence and time management skills. Many candidates know the material but fail due to poor pacing—spending too long on difficult questions and rushing through easier ones.

Weak domain deep-dives: For domains where you scored “Below competent,” don’t just review—rebuild your knowledge from fundamentals. If Infrastructure Security was problematic, start with basic networking concepts, then layer on AWS-specific implementations. Understand not just what each security control does, but when to use it versus alternatives.

Real-world correlation: Connect exam topics to actual business scenarios. Understanding that GuardDuty detects cryptocurrency mining isn’t enough—you need to know how this detection fits into broader incident response procedures, what automated responses are appropriate, and how to balance security with operational continuity.

Teaching and discussion: Join study groups or online communities where you can explain concepts to others. Teaching forces you to understand material deeply enough to articulate it clearly. If you can’t explain why AWS WAF is preferable to security groups for certain attack patterns, you probably don’t understand the distinction well enough for exam success.

FAQ

Q: Can I take SCS-C02 at a different testing center for my retake? A: Yes, you can schedule your retake at any Pearson VUE testing center or choose remote proctoring, regardless of where you took your first attempt. However, ensure your chosen location has reliable availability—popular centers book out weeks in advance. Remote proctoring offers more scheduling flexibility but requires a controlled testing environment for the full 170 minutes.

Q: Will my retake have the same difficulty level as my first attempt? A: SCS-C02 maintains consistent difficulty standards across all attempts. However, question distribution might feel different based on your improved knowledge areas. Topics that seemed impossible on your first attempt might feel manageable after focused study, while previously easy domains might present new challenges. AWS uses psychometric analysis to ensure equivalent difficulty across different question sets.

Q: Should I retake SCS-C02 immediately after the waiting period or wait longer? A: Wait longer if you scored “Below competent” in three or more domains or if your overall preparation was insufficient. The 14-day minimum doesn’t mean optimal timing. Most successful retakers wait 4-8 weeks to properly address knowledge gaps. Consider your first attempt a diagnostic test—use the extended time for comprehensive preparation rather than rushing into a second failure.

Q: If I pass SCS-C02 on my retake, does my certification show that I failed previously? A: No, your AWS certification credentials and digital badge show only that you passed SCS-C02. There’s no indication of previous failures or the number of attempts required. Your certification is valid for three years regardless of whether you passed on your first try or fifth try. Only you and AWS have records of previous attempts.

Q: Can I see my exact numerical score on a retake, or just the same pass/fail domains? A: AWS provides the same score report format for retakes—pass/fail status plus domain-level performance indicators (Above competent/Competent/Below competent). You won’t receive exact numerical scores on any attempt. However, your domain performance indicators might show improvement in areas where you focused additional study between attempts, helping you track preparation effectiveness.
