The Archdiocese of Detroit is committed to increasing student achievement, monitoring student growth, and providing strong differentiated instruction to ALL students in the areas of early literacy, reading, and math. These efforts support the Diocese’s mission to “unlock students’ full potential.”

In an effort to ensure that all teachers have effective tools to meet the needs of all the learners in their classrooms, the Archdiocese will implement the use of a Computer Adaptive Assessment (CAA).

OLGC was chosen as a pilot school for a MAP® Growth™ test from NWEA® and began students’ assessments the winter of 2019.  We give students MAP Growth tests to determine their instructional level and to measure academic growth throughout the school year (and from year to year) in Reading, Mathematics, and Science (Grades 5 and 7).

MAP Growth tests are unique in that they adapt to your child’s level of learning. If your child answers a question correctly, the next question is more challenging. If they answer incorrectly, the next one is easier. This results in a detailed picture of what your child knows and is ready to learn—whether it is on, above, or below their grade level.

Since MAP Growth tests provide immediate and accurate information about your child’s learning, it’s easy for teachers to identify students with similar scores that are generally ready for instruction in similar skills and topics, and then plan instruction accordingly.

MAP Growth reports also provide typical growth data for students who are in the same grade, subject, and have the same starting performance level. Students in grades Kindergarten through Eighth Grade take the tests in the Fall, Winter, and Spring.


IOWA ASSESSMENTS provides a nationally norm-referenced measure of a student's basic skills. The faculty uses this test to evaluate the effectiveness of the curriculum and the learning styles of individual students. The administration also used these results to gauge the overall achievement of our students in relation to those across the country. However, one test alone cannot indicate a student's overall strengths or weaknesses. A more complete picture is gained by observing trends over several years.
