The purpose of the Maine Assessment of Educational Progress (MAEP) in 1972 was to complete the first phase of a 10-year comprehensive needs assessment program involving students in public and non-public schools of the state. The total program is designed to provide specific information about knowledge, skills, understandings, and attitudes in 10 subject areas. The first phase investigated the areas of Citizenship and Writing, using a state-wide probability sample of Maine's 17-year-old student population and the National Assessment of Educational Progress (NAEP) model. This report discusses sampling considerations, exercise package development, administration and scoring, data analysis plan, descriptive analyses, comparisons with National assessment, and within Maine analyses. The overall Citizenship results showed that there was a tendency for the Maine students to surpass national performance on concern for the well-being of others and respect for their rights as individuals. With respect to the Writing results, it is concluded that more emphasis on scholastic writing opportunities is needed to align Maine student performance with that of the Northeast region and the nation.
