Assessment Methodology

Understanding our IQ assessment and development approach

Founding Member Program - Preliminary Scoring Phase

Thank you for being a founding member! You are among the first 100 participants helping establish empirical norms for this assessment. Your IQ score is currently preliminary and calculated using theoretical norms based on cognitive science principles. While your score uses established psychometric frameworks (CHC theory, standard IQ scale Mean=100, SD=15), it should be considered an estimate until we complete norming studies with sufficient sample size (Phase 3 of our roadmap).

What this means: Your cognitive profile pattern and domain strengths/weaknesses are reliable and meaningful. Population-referenced precision (percentiles, age adjustments) will improve as we gather empirical data at milestones: 100 participants (initial norms), 2,000+ (validated norms).

Understanding Your IQ Score

What we measure and how we measure it

What is an IQ Assessment?

Intelligence Quotient (IQ) assessments measure cognitive abilities across multiple domains. Our assessment is built on the Cattell-Horn-Carroll (CHC) theory—the most comprehensive and empirically supported model of human cognitive abilities in modern psychometrics.

The Seven Cognitive Domains We Measure

Unlike many online tests that focus on a single ability type (often only pattern recognition), we assess a broad spectrum of cognitive functions:

  • Fluid Reasoning (Gf): Novel problem-solving, logical deduction, and pattern recognition without relying on prior knowledge.
  • Crystallized Intelligence (Gc): Acquired knowledge, vocabulary, and general information accumulated through education and experience.
  • Quantitative Reasoning (Gq): Mathematical problem-solving, numerical operations, and quantitative thinking.
  • Visual-Spatial Processing (Gv): Mental rotation, spatial reasoning, and visualization of objects in space.
  • Working Memory (Gwm): Active mental manipulation of information, mental calculation, and short-term storage capacity.
  • Processing Speed (Gs): Rapid and accurate cognitive processing, visual scanning, and symbol manipulation.
  • Logical Reasoning (Gf-RG): Deductive reasoning, formal logic, syllogistic reasoning, and drawing valid conclusions from stated premises.

The IQ Scale

Your overall IQ score is reported on the standard scale (Mean=100, SD=15) used by clinical instruments like the WAIS-IV and Stanford-Binet for interpretability. However, our assessment uses different item types and administration methods, so scores should not be directly compared to clinical IQ tests:

  • Mean (Average): 100
  • Standard Deviation: 15 points
  • Score Range: 40-160

Why "Preliminary"?

Your score is calculated using Classical Test Theory (CTT) with difficulty-weighted scoring and the established CHC theoretical framework. Item difficulties are currently based on theoretical estimates and will be empirically calibrated as we collect participant data. However, precise IQ scoring requires large-scale norming studies to refine item parameters through empirical calibration and establish population-referenced norms.

We're currently in Phases 1-2 of a 3-phase validation process (see roadmap below). Your score reflects:

  • Real cognitive assessment across 7 domains
  • Questions designed using established CHC theory and cognitive science research
  • Difficulty-weighted scoring where harder items contribute more points
  • Theoretical item difficulties that will be refined with empirical data
  • Ongoing calibration as we collect more responses

Criterion-Referenced vs. Norm-Referenced Scoring

Your preliminary score uses criterion-referenced interpretation: it estimates your cognitive ability based on the difficulty levels you mastered, compared to theoretical expectations. This is valid and meaningful for understanding your cognitive profile.

Norm-referenced scoring (available after 100+ participants) compares your performance to actual population distributions, enabling percentile rankings and age-adjusted scores. Both approaches are scientifically valid—they serve different purposes.

Founding Member Program

Be part of IQ assessment history

The first 100 participants in IQ Academy Pro are founding members who play a critical role in establishing this assessment as a research-grade instrument.

What You Receive as a Founding Member

  • Immediate access to your cognitive profile and preliminary IQ estimate
  • Updated score reports automatically delivered as norms are established (at 100, 1000, and beyond)
  • Founding member recognition with exclusive tier badge based on your member number
  • Priority access to future assessment features and research updates

Your Contribution to Cognitive Science

By completing this assessment, you contribute data that enables:

  • Score distributions: Establishing what's typical vs. exceptional
  • Item calibration: Refining question difficulty and discrimination
  • Demographic norms: Age- and education-adjusted comparisons
  • Reliability validation: Ensuring consistent, stable measurement
  • Fairness analysis: Detecting and eliminating bias

Transparency promise: We will always clearly communicate what your scores represent at each norming phase. We believe early participants deserve both immediate insights AND the benefit of progressively refined scores as our dataset grows.

Path to Full Validation: 3-Phase Development

We're building this assessment in three distinct phases, following established best practices in psychological test development. Here's where we are and where we're going:

Phase 1: Foundation & Architecture (COMPLETE)

  • CHC-aligned 7-domain framework design
  • Extensive item bank spanning all cognitive domains with multiple difficulty levels
  • Multiple question formats per domain (pattern recognition, matrix reasoning, verbal analogies, etc.)
  • Psychometric scoring algorithms with difficulty weighting
  • Theoretical item difficulty estimates established

Phase 2: Empirical Calibration & Norming (IN PROGRESS)

Target: 2,000+ demographically diverse participants

Phase 2a: Founding Member Phase (Participants 1-100)

Current Status: Active enrollment

  • Establish baseline score distributions across all domains
  • Initial item analysis (difficulty, discrimination, reliability)
  • Identify problematic items requiring revision
  • Begin demographic data collection (age, education, geography)
  • Participants receive criterion-referenced scores (performance relative to expected difficulty levels)

Phase 2b: Initial Norming (Participants 100-1000)

Estimated Start: After 100 completions

  • Begin empirical IRT calibration with sufficient sample size
  • Establish preliminary population norms (percentile rankings)
  • Refine item parameters based on response patterns
  • Conduct differential item functioning (DIF) analysis for fairness
  • Early reliability studies (internal consistency, parallel forms)
  • Participants receive preliminary norm-referenced scores

Your Participation MattersEvery assessment completed in Phase 2 improves our normative database and item calibration. Founding members (1-100) will automatically receive updated scores when initial norms are established.

Phase 3: Professional Norming & Validation (FUTURE)

Target: 1000+ participants | Estimated Start: 2025-2026

  • Establish professionally-stratified norms by age, education, and other demographics
  • Complete full IRT calibration using maximum likelihood estimation
  • Optimize domain weights through confirmatory factor analysis (CFA)
  • Calculate precise percentile rankings with standard error bands
  • Establish test-retest reliability (temporal stability over 6-12 months)
  • Validate internal consistency (Cronbach's alpha ≥ 0.90 for composite, ≥ 0.80 for domains)
  • Conduct convergent validity studies (correlations with established measures)
  • Publish technical manual with full psychometric documentation

At completion of Phase 3, scores transition to "Validated Norm-Referenced" status.

Our Transparency Commitment

Unlike many online IQ tests that make unsubstantiated claims about accuracy, we're building this assessment in the open with full transparency about our development status. You know exactly what phase we're in, what your score represents at each milestone, and how we're progressing toward professionally validated norms. We update this roadmap regularly as we reach new milestones.

Interpreting Your Preliminary IQ Score

Appropriate Uses

Your preliminary IQ score is suitable for:

  • Personal insight & self-understanding of cognitive strengths and weaknesses
  • Educational planning and identifying areas for skill development
  • Curiosity & intellectual exploration with a scientifically-grounded assessment
  • Tracking cognitive development over time (with appropriate intervals)
  • Giftedness screening as preliminary indication that warrants follow-up with clinical assessment (not for educational placement decisions)

Inappropriate Uses

Your preliminary IQ score should NOT be used for:

  • Clinical diagnosis or medical decisions
  • Educational placement or eligibility decisions
  • Employment screening or hiring decisions
  • Legal or forensic proceedings
  • Direct comparison with clinical IQ scores (different methods and norms)

When to Seek Clinical Assessment

Consider a formal evaluation by a licensed psychologist if you need scores for legal, educational, or medical purposes, are concerned about developmental delays, require accommodations, or want highly precise measurement with narrower confidence intervals (±6-8 points vs. ±15-20 points).

Questions or Feedback?

We're committed to transparency about our assessment development. If you have questions about our methodology or want to provide feedback, we'd love to hear from you.
