The Most Important Thing to Understand First

Before diving into any specific number, it helps to know whether the score represents a child’s performance compared to a fixed standard (criterion-referenced) or compared to other students (norm-referenced).

Tests like MAP and STAR are norm-referenced: they tell you how your child compares to a national group. Both types of information are useful, but they answer different questions.
