Neutral round-up
Five platforms compared on pricing, defensibility, and fit: JobCannon (88 assessments, flat-rate), Predictive Index (the PI behavioural and cognitive default), Hogan (derailer-anchored, enterprise gold standard), Criteria Corp (SMB-accessible defended battery), and TestGorilla (broad skills-test library). Each gets an honest paragraph on where it wins — this is a round-up, not a sales pitch.
Pre-employment assessment platforms split by psychometric rigour, price tier, and breadth. Predictive Index and Hogan are the long-validated defended-selection incumbents — PI lists at $1,250+/mo on starter, Hogan at $50K+/year enterprise — both backed by decades of validation research and the conservative choice for high-stakes US hiring screens where disparate-impact challenges are likely. Criteria Corp is the SMB-accessible defended option at roughly $1,200/year for small-business packages, with published validation studies across its cognitive and personality batteries. TestGorilla offers a broad library of skills, personality, and cognitive tests at $25-100/mo per recruiter on starter tiers, with mixed rigour across the catalogue and strong ATS coverage. JobCannon sits structurally apart at $199/mo flat for unlimited assessments — 53 validated instruments shipping standard, positioned for career discovery, team development, and lower-stakes pre-employment use rather than as a defended high-volume hiring screen. None of the five is wrong — the structural decision is whether you need a defended selection instrument (PI, Hogan, Criteria) or a broader-use development and screening platform (JobCannon, TestGorilla).
Where the round-up diverges.
What ships across the five platforms — JobCannon's 53-instrument battery alongside the focused selection-anchored batteries of PI, Hogan, and Criteria.
Three of the five platforms shown as cost reference points. JobCannon Scale at $2,388/year flat sits structurally outside per-recruiter and enterprise pricing.
JobCannon Scale at $2,388/year covers unlimited assessments — hiring screening, team development, and coaching on the same platform. For high-stakes US selection screens prefer one of the long-validated defended-selection options (PI, Hogan, or Criteria Corp).

A pre-employment assessment platform delivers validated psychometric and cognitive tests to job candidates as part of the hiring pipeline, with the goal of predicting on-the-job performance and fit beyond what a resume or interview reveals. Typical use cases include cognitive-ability screening (problem-solving, learning agility), personality measurement (work style, conscientiousness, derailers under pressure), skills testing (coding, writing, language), and behavioural simulations (situational judgement). Hiring teams use them at three stages: top-of-funnel screening to narrow large applicant pools, mid-funnel selection to inform interview structure, and final-stage validation before offer. The platforms vary in psychometric rigour, EEOC and ADA defensibility, ATS integration depth, candidate experience, and price model (per-test, per-seat, or flat enterprise).
EEOC defensibility matters when an assessment is used as a hiring screen and could be challenged on disparate-impact grounds. Predictive Index and Hogan are the two platforms in this round-up with the most established psychometric validation, validity-generalization studies, and documented EEOC defensibility — both have decades of validation research backing their use in selection. Criteria Corp similarly publishes validation studies for its cognitive and personality batteries. TestGorilla offers a broad library of skills and personality tests with mixed rigour across the catalogue. JobCannon ships 53 validated assessments and is positioned for career discovery and team development rather than as a defended hiring-selection instrument — for high-stakes US hiring screens where disparate-impact challenges are likely, the more conservative choice is one of the long-validated platforms. For lower-stakes use (development, coaching, team-building, candidate self-discovery before applying) any of the five fits.
For a 50-employee SMB hiring at modest volume (1-2 hires per month), the most-deployed entry points are TestGorilla at roughly $25-100/mo per recruiter on its starter tiers, Criteria Corp at around $1,200/year for SMB packages, and JobCannon Scale at $199/mo flat for unlimited assessments. Predictive Index at $1,250+/mo and Hogan at $50K+/year are structurally priced for larger employers and are typically overkill at 50 employees. The structural decision at SMB scale is whether you need a defended hiring-screen instrument (Criteria Corp is the most accessible of the three EEOC-defensible options) or a broader-use assessment platform that covers candidate screening plus team development plus coaching (JobCannon or TestGorilla). Most 50-employee SMBs are better served by the broader-use platforms because hiring volume rarely justifies dedicated screening infrastructure.
Meta-analytic research consistently shows that general cognitive ability (GCA) is the single strongest predictor of job performance across most roles, with personality traits — particularly conscientiousness — adding meaningful incremental validity. The practical takeaway is that a well-designed hiring assessment programme typically combines both: cognitive screening at top of funnel to predict learning and problem-solving, plus personality measurement at mid-funnel to inform fit, derailers, and team dynamics. Criteria Corp, Predictive Index, and Hogan all ship integrated cognitive plus personality batteries. TestGorilla lets you assemble a custom battery from its catalogue. JobCannon ships both cognitive (IQ, critical thinking, numerical reasoning, abstract reasoning) and personality (Big Five, MBTI, DISC, plus 45+ other instruments) but is positioned for self-discovery and development rather than as a defended selection instrument.
ATS integration matters when assessment scores need to flow back into the recruiter workflow rather than living in a separate tool. Predictive Index, Hogan, and Criteria Corp all ship native integrations with the major ATS systems — Greenhouse, Lever, Workday, iCIMS, SuccessFactors, BambooHR — letting recruiters see assessment scores directly on candidate profiles. TestGorilla integrates with most major ATS platforms and additionally offers Zapier and webhook coverage for less-common systems. JobCannon currently supports webhook-based score export and ATS integration on Enterprise tier, with native integrations being added based on customer demand. For a hiring programme where ATS is the primary recruiter workflow, native integration depth is a real differentiator; for hiring programmes where assessment scores are reviewed in-platform alongside other context, webhook export is usually sufficient.
