FrameworkRICAS mathematics in grades 3–8 is the Rhode Island-administered version of Massachusetts MCAS math, and RIDE states the Massachusetts framework is strongly aligned with Rhode Island’s Common Core-based mathematics standards. The released-item documents report results under the same framework domains used by the Massachusetts Curriculum Framework for Mathematics.
Blueprint & weightingThe official source reviewed here did not publish domain percentage weights in the pages/documents retrieved. The released-item documents do state that mathematics results are reported under five MCAS reporting categories identical to the framework domains.
