Standardized testing widens educational inequity

Quality and quantity of direct evidence for or against the claim — RCTs, systematic reviews, natural experiments, large cohort studies.

College Board and Chetty et al.'s (2023) admissions data documenting scores rising monotonically with family income provide direct, well-sourced support.

Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?

The resource-advantage-to-score mechanism is validated through test-prep access differentials and Card & Giuliano's (2016) finding that universal screening substantially changes gifted-program demographics, showing scores partly reflect access rather than pure ability.

Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.

Broad agreement that standardized tests reflect resource access, though genuine debate persists on whether test-optional alternatives reduce or worsen the underlying inequity.

Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.

The income-score gradient replicates across SAT, ACT, and gifted-program screening data across multiple cohorts and testing regimes.
