CTS Exam Scoring Explained: Understanding the 350/500 Point System and Pass Rates
The Certified Technology Specialist (CTS) exam scoring system can initially seem confusing to many candidates. Why does AVIXA use a 350 out of 500 point system instead of a simple percentage? How does this translate to actual performance, and what does it mean for your preparation strategy? This comprehensive guide demystifies the CTS scoring methodology and provides actionable insights to help you achieve certification success.
Understanding the CTS Scoring Framework
The 350/500 Point System Explained
The CTS exam requires a minimum score of 350 out of 500 points to pass. This represents a 70% passing threshold, but the scoring mechanism is more sophisticated than a simple percentage calculation.
Key Scoring Facts:
- Total Possible Points: 500
- Minimum Passing Score: 350 points
- Passing Percentage: 70%
- Exam Questions: 100 multiple-choice questions
- Time Limit: 2 hours (120 minutes)
Why Scaled Scoring Instead of Raw Percentages?
AVIXA employs a scaled scoring system rather than raw percentages for several critical reasons:
1. Question Difficulty Adjustment Not all exam questions carry equal weight. The scoring algorithm accounts for:
- Statistical difficulty of individual questions
- Discrimination index (how well questions differentiate between qualified and unqualified candidates)
- Historical performance data across all test-takers
2. Exam Form Equating Multiple versions of the CTS exam exist to maintain security. Scaled scoring ensures:
- Consistent difficulty across different exam forms
- Fair comparison between test-takers regardless of which version they receive
- Protection against minor variations in question difficulty
3. Measurement Precision Scaled scores provide:
- More accurate assessment of candidate competency
- Reduced impact of guessing on final scores
- Better alignment with industry competency standards
Detailed Scoring Methodology
How Points Are Calculated
The CTS scoring process involves multiple sophisticated steps:
Step 1: Raw Score Calculation
Raw Score = Number of Correct Answers (out of 100 questions)
Step 2: Statistical Analysis Each question undergoes psychometric analysis including:
- Item Difficulty (P-value): Percentage of candidates who answer correctly
- Item Discrimination: How well the question differentiates between high and low performers
- Point-Biserial Correlation: Statistical relationship between individual question performance and overall exam success
Step 3: Scaled Score Conversion The raw score is converted to a scaled score using a pre-determined conversion table that accounts for:
- Overall exam difficulty
- Question performance statistics
- Historical norm data
Sample Scoring Scenarios
To illustrate how scaled scoring works in practice, consider these examples:
Scenario A: Standard Difficulty Exam
- Raw Score: 75/100 correct answers (75%)
- Scaled Score: 375/500 points
- Result: PASS (exceeds 350 minimum)
Scenario B: High Difficulty Exam
- Raw Score: 72/100 correct answers (72%)
- Scaled Score: 365/500 points
- Result: PASS (scaled up due to higher difficulty)
Scenario C: Lower Difficulty Exam
- Raw Score: 75/100 correct answers (75%)
- Scaled Score: 355/500 points
- Result: PASS (scaled down due to easier questions)
Scenario D: Borderline Performance
- Raw Score: 69/100 correct answers (69%)
- Scaled Score: 348/500 points
- Result: FAIL (below 350 minimum)
Understanding Percentage Variations
Why Your Percentage May Vary
Many candidates are surprised when their passing percentage doesn't exactly equal 70%. Here's why this occurs:
1. Question Weighting Differences

2. Performance Domain Variability Your scaled score reflects performance across different competency areas:
- Strong Performance: Compensation for weaker areas
- Weak Performance: May require higher overall accuracy
- Balanced Performance: Most predictable scoring outcome
3. Adaptive Scoring Algorithms The scoring system accounts for:
- Question Interaction Effects: How performance on one question influences others
- Content Area Minimums: Ensuring basic competency across all domains
- Ceiling and Floor Effects: Preventing extreme scores from distorting results
Real-World Scoring Examples
Based on historical data and candidate reports, here are typical scoring patterns:
High Performer Profile:
- Raw Score: 82-85/100 (82-85%)
- Scaled Score: 410-435/500 points
- Performance: Consistent strength across all domains
Solid Pass Profile:
- Raw Score: 74-78/100 (74-78%)
- Scaled Score: 365-385/500 points
- Performance: Good overall with 1-2 weaker areas
Narrow Pass Profile:
- Raw Score: 70-73/100 (70-73%)
- Scaled Score: 350-365/500 points
- Performance: Mixed results requiring strategic preparation
Narrow Fail Profile:
- Raw Score: 67-69/100 (67-69%)
- Scaled Score: 330-348/500 points
- Performance: Close but needs focused improvement
Evaluation Questions and Non-Scored Items
Understanding Pretest Questions
Each CTS exam includes approximately 15-20 evaluation questions that do not count toward your final score. These serve important purposes:
1. Future Question Development
- Test new questions for statistical validity
- Gather performance data for future exam forms
- Ensure question quality before official inclusion
2. Exam Security
- Prevent candidates from identifying scored vs. non-scored questions
- Maintain test integrity across multiple administrations
- Support continuous exam improvement
3. Statistical Calibration
- Establish difficulty baselines for new content
- Validate question performance across diverse candidate populations
- Support psychometric analysis and scaling procedures
How to Handle Unknown Question Types
Since you cannot identify which questions are evaluative, follow these strategies:
Treat Every Question Equally:
- Maintain consistent effort across all 100 questions
- Don't attempt to guess which are evaluation items
- Use full time allocation for thorough consideration
Focus on Learning Opportunities:
- View challenging questions as learning experiences
- Even evaluation questions test relevant knowledge
- Use them to identify knowledge gaps for future study
