You mention assessments. Is this a lot of standardized testing? My child doesn't do well on tests.
We use multiple forms of data to assess student learning and growth. Sometime that is a standarized test, like the one you will take for admission to the school. But it can also be, for example, a presentation, a portfolio of work, a video, or a student-built web page, for example. Part of our custom approach is determining what kind of assessment your child can best present in order to show us that they have mastered the material.
