Valid, Reliable & Defensible Testing
From job analysis to long-term maintenance, we apply proven statistical methods tailored to your goals. Whether you're launching a new credential or strengthening an existing one, we ensure quality and compliance every step of the way.
Item Development & Review
Item Development & Review
Item Creation and Expert Review
We develop high-quality items aligned with content domains and validate them through expert input.
Sensitivity and Bias Review
We review items for cultural, linguistic, and other biases to ensure fairness and equity.
Content Validation
Items are reviewed by experts to confirm they measure the intended content and skills.
Cognitive Interviewing / Think-Aloud Protocols
We analyze examinee thought processes to improve item clarity and reduce ambiguity.
Pretesting and Preliminary Analysis
Pretesting and Preliminary Analysis
Preliminary Item Analysis
We assess item performance to flag weak or ineffective items before live use.
Pilot Testing / Field Testing
Test items are trialed under real conditions to confirm functionality and fairness.
Item Drift and Fairness Analysis
We monitor changes in item performance over time to maintain test consistency.
Item Drift Analysis
We detect items with shifting performance to ensure long-term test validity.
Differential Item Functioning (DIF) Detection
Differential Item Functioning (DIF) Detection
Mantel-Haenszel Method
This statistical method detects item-level performance differences between groups.
IRT-Based DIF
We use item response theory to evaluate fairness across diverse test-taker populations.
Logistic Regression DIF
Regression-based DIF analysis helps isolate bias while accounting for ability levels.
Differential Person Functioning (DPF)
We flag individuals whose response patterns deviate from expected norms.

Equity and Fairness Evaluations
Item and Person Calibration Modeling
We align item difficulty and person ability using calibrated psychometric models.
IRT Calibration
We place items on a common scale for consistency and adaptive testing readiness.
Person Fit Analysis
We detect unusual response patterns that may signal test irregularities.
Test Design and Assembly
Test Blueprint and Specification Development
We define test content, structure, and difficulty to match your objectives.
Automated and Manual Test Form Construction
We build test forms that meet specifications using both manual and automated tools.
Test Form Equating, Linking, and Scaling
We ensure score comparability across different forms and testing cycles.
Lexile / Readability and Complexity Score Estimation
We evaluate content for appropriate reading and cognitive levels.
Automatic Enemy Item Detection
We identify items that may clue responses to others to protect test integrity.
Linear and Adaptive Test Assembly (e.g., CAT, MST)
We design both traditional and adaptive tests for flexibility and precision.
Job Analysis and Standard Setting
Job Analysis and Standard Setting
Job Task Analysis (JTA)

Operational Testing and Monitoring
Operational Testing and Monitoring
Test Security Analysis
We analyze patterns and behaviors to detect and mitigate test security threats.
Test Collusion Detection
Our tools flag suspicious response similarities that may indicate candidate collusion.
Pre-knowledge Detection
We identify unusual performance that may suggest unauthorized access to test content.
Anomalous Test Behavior Analytics
We monitor for inconsistent timing, guessing patterns, and other behavioral anomalies.
Erasure Analysis (for paper-based tests)
We evaluate answer changes to identify irregular patterns that may raise security concerns.
Remote Proctoring Analytics
Our platform integrates data from remote proctoring to support test integrity and compliance.
Real-Time Data Forensics
We provide live monitoring and alerts for immediate response to potential testing issues.
Reporting and Interpretation
Psychometric and Technical Reports
We deliver detailed documentation on test reliability, validity, and development processes.
Score Reporting and Interpretation Guides
We provide clear explanations of scoring and meaning, tailored for all stakeholder audiences.
Validity and Reliability Documentation
We compile and organize the evidence needed to support responsible test use.

Stakeholder Presentation Support
We help translate technical data into actionable insights for boards, committees, and decision-makers.
Ongoing Evaluation and Quality Assurance
Ongoing Evaluation and Quality Assurance
Longitudinal Trend Analysis
We track score trends and item performance over time to ensure test quality and relevance.
Test Recalibration and Refresh Cycles
We regularly review and update test content to reflect evolving standards and best practices.
Continuous Quality Monitoring
Our analytics help identify early signs of drift or quality issues before they impact results.
