## Assessment Systems (assess.com)

Assessment Systems is a US-based assessment technology and consulting company whose platform is built for organizations running high-stakes, high-volume exams: certification boards, government HR and licensure bodies, pre-employment programs, universities, and K-12 assessment programs. The core product, FastTest, covers the full assessment lifecycle, from authoring and reviewing items in large banks to assembling test forms, publishing them securely, and analyzing results.

The platform goes well beyond basic multiple-choice quiz software. It supports modern psychometrics such as item response theory (IRT), computerized adaptive testing (CAT), multistage testing (MST) and LOFT, online essay marking, and AI-assisted tools for item development and content detection. Delivery-side features include live and recorded remote proctoring, a test center network, lockdown and watermarking security controls, and a white-label, embeddable engine so organizations can keep their own branding.

On top of the software, Assessment Systems sells consulting: job task analysis, item writing, Angoff standard-setting studies, psychometric analysis, test security audits, and full certification program management. Companion products like Iteman (CTT analysis), Xcalibre (IRT software), and TestAssembler support classical and modern analysis workflows, while the Credicycle candidate portal handles applications, payments, badge issuance, and renewals. Pricing is quoted per engagement.

**Pricing & Plans:** Custom quote only — Assessment Systems does not publish list prices. Prospects are asked to talk to an expert or request a demo; costs depend on exam volume, modules, and consulting scope.

- **Item banking and authoring:** Manage large item pools with metadata, versioning, SME workflow and dozens of item types, plus AI-assisted authoring tools.
- **Secure test delivery:** Deliver high-stakes exams with lockdown browsers, watermarks, AI detection, MFA and configurable scheduling across locations and institutions.
- **Adaptive and personalized exams:** Support IRT-based CAT, multistage testing (MST) and LOFT models for shorter, more precise exams.
- **Proctoring and test centers:** Choose live or recorded remote proctoring, bring your own proctor, or use Assessment Systems' global test center network.
- **Psychometric consulting:** In-house experts deliver job analysis, item writing, Angoff cutscore studies, IRT analysis and NCCA/ISO-aligned validation.

**Strengths:** Covers the whole assessment lifecycle in one platform, from item banking through reporting; Genuine in-house psychometric expertise with IRT, CAT and standard-setting services; Strong security and proctoring options, including remote proctoring and a test center network; White-label and embeddable engine plus APIs for integrations like ATS

**Limitations:** No public pricing; buyers must go through a sales conversation; Enterprise-focused tooling is heavier to learn than simple quiz builders; Consulting services and custom modules can make total cost hard to predict upfront
