maat: An R Package for Multiple Administrations Adaptive Testing.

Multiple Administrations Adaptive Testing (MAAT) is an extension of the shadow-test approach to CAT for the assessment framework involving multiple tests administered periodically throughout the year. The maat package utilizes multiple item pools vertically scaled across grades and multiple phases (stages) within each test administration, allowing for transitioning from an item pool to another as deemed necessary to further enhance the quality of assessment.
