An alternate assessment may be appropriate. Reading a math word problem to a student, however, who then completes the computation themselves, would not invalidate the assessment or require any alternate option. Maine does not have a separate alternate assessment system. MCAS provides for an array of assessment options that may include accommodations and alternate assessment. Validity is the extent to which an assessment measures what is needed for a particular purpose and the results, as they are interpreted and used, meaningfully and thoroughly represent the specified knowledge and skill.
Reliability refers to the consistency or stability of assessment results.
