The Easy Buy pack for KS2 Maths contains 8 copies of each half-termly test for Years 3 to 6. 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.
