Standardized test scores are not the only measure of a school’s quality. These tests are designed to assess an individual student’s performance compared to all students nationally. They do not compare a school’s quality to other schools. Many other factors should affect your decision about which school your child should attend, including: educational philosophy, curriculum quality, teacher credentials, class size, location, cost, availability of resources, discipline policy, opportunities for parental involvement and communications.
In 2012, the Archdiocese of Baltimore updated national norms to calculate the scores. You cannot compare test performance this year to test performance prior to 2012.
