McGlannan School utilizes both formal and informal methods to track our students’ progress from year to year.
At the end of each January, our students take The Iowa Assessments™ (Form E). The Iowa Assessments™ are evidence based, psychometrically sound assessments that measure student achievement and growth against next generation learning standards for grades K–12. This test is widely utilized across the United States as a national assessment tool to assess students’ academic skills. It measures both foundation skills and higher-order thinking skills in the areas of listening, language, reading, vocabulary, word analysis, written expression, spelling, capitalization, punctuation, math concepts and applications, and computation.
The graphs below show how McGlannan students have performed on the Iowa Assessments™ in five successive years from 2022 to 2026. This longitudinal study tracked student progress in the same subject areas annually utilizing the 2024 norms, which are the most up-to-date national comparisons of student performance. These norms include private schools, public schools and students without special needs across the United States.
Normal student growth from grade to grade would appear as a horizontal line (see the black dotted reference line indicating the national average). McGlannan student growth, represented by each of the solid-colored lines, has an upward trajectory. This indicates that in the areas of English Language Arts (ELA) and Mathematics, McGlannan students surpass the expected student growth.
Overall, the data indicates that extended time spent in the McGlannan School educational program leads to compound academic gains, helping students move from below-average starting points to performing consistently above the national average in higher grades.
