When utilizing common formative assessments to collect data on student progress, teachers can compare their students' results. In tandem, they can also share the strategies they used in the classroom to teach that particular concept. With these things in mind, the teacher team can make some evaluations on what tasks and explanations seemed to produce the best student outcomes. Teachers who used alternate strategies now have new ideas for interventions and for when they teach the topic in upcoming years. Teacher teams can also use common formative assessments to review and calibrate their scoring practices. Teachers of a common class should aim to be as consistent as possible in evaluating their students. Comparing formative assessments, or having all teachers evaluate them together, is a way for teachers to adjust their grading criteria before the summative assessment. Through this practice, teachers are presented with an opportunity to grow professionally with the people who know them and understand their school environment.
