Published Validity Research	Extensive. Multi-decade research programme published in IELTS Research Reports series, Cambridge Assessment research reports, and peer-reviewed journals. Covers construct validation, scoring quality, test impact, and test preparation effects	TOEFL iBT Technical Manual (Manna et al., 2025) presents a formal validity argument across six hierarchical inferences (Chapelle, 2008 framework). Developed through iterative prototyping (N=570), pilot testing (N=700), and field testing (N≈5,000). Described as a living document. Broader ETS TOEFL research base spans decades	Pearson publishes technical reports and research papers through the Pearson Research and Innovation team. Topics include scoring validity, CEFR alignment, and AI scoring quality	Limited published research in the public domain. Technical documentation available on request	Growing body of research. Duolingo Research publishes technical reports and peer-reviewed papers on scoring validity, item design, and test security	Some published technical reports, including CEFR alignment documentation. Independently published research is limited	Limited publicly available validity research. Some technical documentation exists	Oxford University Press publishes research reports, including CEFR alignment studies. Some peer-reviewed publications are available
Predictive Validity	Studied extensively. Multiple studies document moderate positive correlations between IELTS scores and indicators of academic success (grades, progression, programme completion)	Predictive validity evidence for the January 2026 version planned for collection during the operational phase. The legacy TOEFL iBT has an extensive base of published predictive validity studies	Some studies report correlations between PTE Academic scores and academic outcomes. Evidence base is growing	Limited published data on the relationship between Password scores and academic success	Early studies indicate moderate correlations between Duolingo English Test scores and academic outcomes. Evidence base is developing	Limited published data on predictive validity for academic success	Limited published data on predictive validity for academic success	Some studies have been published. Evidence base is developing
Construct Validity	Strong. Published evidence includes factor analyses, content validity studies, and criterion-related validity studies accumulated over multiple decades	Initial evidence includes content-construct alignment analysis and rubric-score correspondence. Section-level reliability: Reading 0.86, Listening 0.88, Writing 0.87, Speaking 0.94, Overall 0.90. Factor analysis studies planned for the operational phase	Pearson’s technical reports include factor analyses, correlation studies, and documentation of construct representation across item types	Technical documentation describes alignment of the test construct to academic English demands. Independent verification is limited	Duolingo’s technical reports describe the IRT model underpinning the adaptive algorithm and construct coverage across item types	CEFR alignment documentation published. Some construct validity evidence reported in technical materials	Technical documentation available. Independent validation is limited	Construct aligned to CEFR. Oxford University Press research reports document alignment studies
Fairness & Bias Research	Published differential item functioning (DIF) analyses. Ongoing fairness monitoring and research into cultural and first-language bias as part of the IELTS research programme	DIF analyses conducted on 1,454 items by gender during development: 21 items flagged, none found to exhibit content bias on review. Field test data showed comparable performance across subgroups. AI scoring found not to disadvantage major first-language subgroups	Pearson reports fairness analyses in technical documentation.
