IDAT: International Diagnostic & Admissions Test

What IDAT: International Diagnostic & Admissions Test does

IDAT (International Diagnostic and Admissions Tests Pty Ltd), founded in 2018 and headquartered in Sydney, is a privately held online assessment provider focused on K-12 international school admissions. The company operates a six-stage testing suite aligned to K-12 year levels, evaluating English proficiency, mathematics, general ability, and character traits, delivered through a proprietary platform featuring 3D avatar technology and the IDAT Secure 360 remote proctoring system — which uses facial recognition, screen recording, audio monitoring, and a rotating question bank to maintain test integrity. The product family includes the core IDAT test, IDAT Concise (a shorter computer-marked test for bulk cohort screening with 60-minute turnaround), IDAT for IB, IDAT for Scholarship Students, and IDAT for AI (co-developed with University College London, globally launched January 2026).

IDAT monetizes primarily through per-test registration fees paid by students and families or via bulk test codes/vouchers purchased by schools, with ancillary revenue from additional score delivery ($10-$50/school), expedited results ($100 administration fee), remarking/appeals ($200/test), and mock practice tests ($20). Distribution is executed through three dedicated portals — Student, School, and Agent — supporting direct-to-consumer, channel partner (education agents and school networks), and direct sales-led motions simultaneously. The company has established validation by the University of Sydney's Centre for Educational Measurement and Assessment (June 2020) and integration with OpenApply, and serves a globally distributed customer base spanning Australia, the United States, China, Canada, the Middle East, and Latin America. The organization remains very lean at approximately six employees with no disclosed external funding.

Scale indicators3 records

Recent moves5 records

Expansion highlights5 records

Emerging players

• Duolingo English Test: Duolingo English Test is an online, AI-proctored English proficiency test that has gained rapid adoption as a lower-cost, faster alternative to traditional English assessments. It competes with IDAT's English component on delivery model and price, though it is more focused on higher education admissions.
• Oxford ELLT: Oxford ELLT (English Language Level Test) is an online English proficiency test from Oxford University Press, positioned for international student admissions. It overlaps with IDAT's English assessment offering and targets similar schools and student segments.

Others

• International Schools Services (ISS): ISS supports the founding and operation of international schools worldwide, including admissions and student services. It is not a direct competitor but operates adjacent to IDAT in the international K-12 admissions ecosystem.
• OpenApply: OpenApply is an admissions management platform for international schools and is already an integration partner of IDAT. While not a direct assessment competitor, it is a tightly adjacent ecosystem participant through which IDAT reaches schools.

Broad incumbents

• ETS (TOEFL Junior): ETS produces TOEFL Junior and other assessments used in international school admissions and placement. It overlaps with IDAT on English proficiency testing for school-aged learners, with a stronger brand and deeper institutional reach.
• Pearson (PTE / Pearson Test of English): Pearson delivers English and academic assessments used in school and university admissions globally. It competes with IDAT's English proficiency component and offers comparable AI-enabled scoring, but as part of a much larger education services portfolio.
• Cambridge Assessment International Education: Cambridge offers a portfolio of international assessments and qualifications (including Cambridge English and school-level testing) widely recognised by international schools. It overlaps with IDAT on English proficiency and aptitude testing, but as part of a much broader curriculum and credentialing portfolio.

Direct peers

• ERB (ISEE): ERB's ISEE is a leading admissions test for independent and international schools in the US and globally. It directly competes with IDAT for K-12 school admissions slots, with a similar use case of supporting admissions decisions and student placement.
• NWEA (MAP): NWEA's MAP suite provides computer-adaptive K-12 assessments widely adopted by international schools for progress monitoring and admissions screening. It directly competes with IDAT's multi-stage K-12 assessment approach, though MAP is typically used for ongoing progress rather than initial admissions.
• SSAT (SSAT by Enrollment Management Association): SSAT is a widely used K-12 admissions test for private and international schools. Like IDAT, it is positioned as a standardised admissions assessment for school applicants, though SSAT has a longer track record and stronger US brand recognition.
