Assessment is an important step in a student’s learning process. It determines whether or not a student has met the learning intentions. Learning intentions are what the student needs to know/learn by the end of a lesson, unit or year. If the student has not met the learning intentions, it can also help the teacher understand where that student is struggling and make differentiation in their lessons to help meet that student’s needs. Assessment is crucial when it comes to determining student’s grades, abilities, different learning needs, advancement within the curriculum, support and funding.
