How your teen is assessed

Your teen’s learning is assessed using a variety of tools and strategies within the classroom. Ask your teen’s teacher what methods they are using. The different assessment methods tell you and your teen’s teacher about your teen’s strengths, the areas in which they might grow and how well your teen is doing throughout the course. The teacher can then change or refine their teaching plans to ensure that learning activities better meet the needs of your teen. At the end of the course, your teen is assessed and their achievement is reported so that you know if they have achieved the expected learning outcomes for their grade.
