This simulation study examines the measurement precision, item exposure rates, and the depth of the MAP® Growth™ item pools under various grade-level restrictions. Unlike most summative assessments, MAP Growth allows examinees to see items from any grade level, regardless of the examinee's actual grade level. It does not limit the test to items designated for the examinee's actual grade. The purposes of this research study are as follows: (1) To explore different possible test designs using on-grade items only with the current MAP Growth item pools; and (2) To provide recommendations to Content Solutions for developing grade-level items. Specifically, this study evaluates the depth of MAP Growth on-grade item pools along the student ability spectrum based on empirical Rasch Unit (RIT) score distributions. The study manipulated two factors: the type of item pool and type of simulee. Different item pools were created for the simulations with restrictions to explore the feasibility of creating on-grade MAP Growth assessments. Simulee groups were based on on-grade and off-grade student ability.
