Effective teachers are always continuously assessing. These teachers watch how their students are performing and make adjustments to the lesson. The big difference in what will be expected in the future is that learning must be documented rather than exist in the teacher's head. There is no single most effective way to record or report student learning. Many methods exist and you need to choose what works best for you and your students.
Some teachers like to use assessment charts that they post in the gym.
Student names go down the side and the skills go along the top. As students achieve the skills they are given stickers. Many teachers and students find these extremely motivational and informative. The challenge is to break the skills into small enough steps so that all students are able to record progress in their learning. In some settings, older students do not enjoy having their names so visible in the gym.
