Throughout the school year, De Chantal students in second through eighth grade take National Accredited Standardized Tests in Math, Reading and Science. The tests are given three times during the school year. The Fall test provides students, teachers and parents with an understanding of individual students level of understanding. Winter, mid-year testing highlights how students have progressed with new material and late Spring testing, just before the close of the school year, gives an assessment of academic progress made over nine months. Teachers use test results in many ways; they look for trends within their grade and adjust grade-wide lessons accordingly; identify areas of individual student progress and adjust individual student lessons; and review curriculum design to offer student support.
