In CP / 1st and CE1 / 2nd, two ordinary things are happening at once. First, MAP assessments measure English-only, while our students are simultaneously building literacy in French (and Spanish) too. Second, students taking any new adaptive test for the first time typically score lower simply from unfamiliarity with the format, regardless of what school they attend.

Neither is a weakness. Research on multilingual learners consistently finds that the early effort of managing more than one language gives way to advantages in reading comprehension, problem-solving, and focus — advantages that tend to show up later, not in the early grades. Our results tell a consistent story: scores climb steadily every year.
