BASE is a one-to-one assessment between the teacher, teaching assistant or appropriate adult and the child. Ideally, you should do it in a quiet corner, away from the rest of the class, in an environment where the child feels comfortable. A character, “Milly the Bug”, presents the assessment and asks the child questions. However, the adult is in control of the computer at all times and uses the mouse and the on-screen buttons to mark the answers the child gives as right or wrong.
The assessment is adaptive to each child, so, as it progresses, the questions gradually get more difficult. When the child starts getting them wrong, it will stop asking harder questions in that section, move onto the next section, and start again with easier questions.
The assessment doesn’t have to be carried out by the class teacher (although you will learn so much about your pupils if you do), and the same teacher doesn’t need to carry out all of the assessments. Each assessment takes about twenty minutes, and the results return automatically to CEM if you complete the web-only version with the child.
