Accurate assessment is very important to me as a professional. To establish an effective practice to ensure that all the students are assessed appropriately, I would begin with letting all the students know what the objectives of a lesson are as well as how they will be assessed. This will help the students focus on what is important and be able to ask for clarification if needed. It is also important to carefully select what forms of assessment will be used for each lesson and each set of learners.
Some students have troubles taken written tests and expressing their knowledge linguistically.
For this reason it is beneficial to offer many different forms to evaluate student knowledge. This could be in the form of creating a poster displaying their knowledge, having a test taken orally, or having the students work together on a presentation to display their knowledge. It is also important to remember that standardized test are not necessarily the best way to assess students. For this reason the reliability and validity should be taken into consideration. Whenever assessment occurs it should be for a clear purpose and actually assess the objectives of the lesson.
