Assessment & Development Consultants

What Assessment & Development Consultants does

PSI Services LLC is a global testing and assessment services company operating as a subsidiary of ETS (Educational Testing Service). It provides end-to-end solutions spanning test development, multi-modal test delivery, and test security to certification bodies, professional associations, government agencies, healthcare organizations, IT and technology companies, and higher-education clients across the Americas, APAC, and EMEA. Core capabilities include AI-assisted test development and test preparation with human-in-the-loop quality assurance, psychometric test design, online proctoring and remote testing, a global test center network, and a security stack that combines audits, mystery-shopper investigations, statistical data forensics, web crawling, and incident response.

Revenue is generated through a mix of professional services for test development and security, transaction fees for test delivery (per-test), and licensing/royalties for proprietary programs (HiSET, the high school equivalency credential recognized by every U.S. state, and Skills for English, a UK Home Office-approved English proficiency test). The company sells to test owners through enterprise field sales and multi-year contracts, while operating the PSI Online Store and direct-to-consumer programs to capture test-taker spend on prep and scheduling. Customer evidence spans National Board for Respiratory Care, AACN, ISACA, BCEN, NCHEC, ABRSM, the Linux Foundation, the California Department of Real Estate, and the Washington State Office of Insurance Commissioner, among others.

Note on data conflict: the input lists the named entity "Assessment & Development Consultants" with firmographic attributes of 11–50 employees, founded 1988, headquartered in Guildford, UK (website psionline.com, described as a human-resource service), while the remainder of the data — products, technology, customers, parent company, and operating geographies — substantively describes PSI Services LLC. The analysis above is grounded in the PSI Services LLC operational data, which represents the bulk of the input; readers should treat the firmographic block as inconsistent with the operational scale described.

Direct peers

• Kryterion (Webassessor): Direct competitor offering test development, online proctoring and analytics for certification bodies, with a particular focus on association and IT certification programs — closely overlapping with PSI's customer segments.
• Pearson VUE (Pearson): The largest commercial competitor in computer-based test delivery for certification and licensure programs globally. Operates a comparable multi-modal delivery network (test centers plus online proctoring) and competes directly for the same test-owner RFPs (IT, healthcare, government).
• Prometric: Major direct competitor delivering high-stakes exams through owned test centers and remote proctoring across certification, licensure, healthcare and academic programs. Closest comparable in business model and customer profile.

Regional players

• Yardstick Assessment Strategies: Canadian-based assessment and credentialing services firm specializing in licensure and certification programs. Comparable in service scope but primarily serves Canadian and North American regulated professions.

Broad incumbents

• ETS (Educational Testing Service): Parent organization and broader incumbent in educational measurement, offering the GRE, TOEFL, Praxis and other flagship assessments. Overlaps in psychometric capability and certification programs but operates at much larger scale and scope.
• Aon Assessment Solutions: Broader incumbent providing talent assessment, psychometric testing and certification-adjacent services as part of Aon's wider human capital portfolio. Comparable in psychometrics but competes from a consultancy platform.
• SHL (a CEB company, now part of Expleo): Global psychometric assessment provider for hiring, talent and certification use cases. Overlaps with PSI on assessment content and psychometrics but is more focused on pre-employment and talent measurement.

Emerging players

• Questionmark: Provider of enterprise assessment authoring and delivery software, focused on corporate training and certification. Comparable technology stack but smaller scale and different primary buyer.
• Caveon Test Security: Specialist in test security services including forensics, data analysis and item compromise investigations. Competes directly with PSI's test-security franchise (Audits & Investigations, Data Forensics & Web Crawling).
• ProctorU (Meazure Learning): Online proctoring specialist serving higher education and credentialing clients; competes most directly with PSI's online proctoring and remote delivery offerings.
