The Easy Buy pack for KS1 Maths contains 30 copies of each half-termly test for Years 1 and 2. In Year 1 there is a single test per half term. From Year 2 there are two tests per half term: one for arithmetic and one for Problem Solving and Reasoning.
The tests are only part of the Progress & Assess picture. The marking guidance is contained in the Teacher's Guide, which you can purchase as a printed booklet, or access online as part of your subscription to Progress & Assess on ActiveLearn Primary. ActiveLearn Primary is also where you input your test results and generate reports that tell you how each of your pupils is performing against age-related expectations, and how they are progressing across time.
