Probability data for Year 2 and Year 6 Progress will be calculated each year, after the test has been sat.

Thresholds provided for Year 3, 4, 5 and Year 6 science will be set in the first year of the test and will not change until the tests change. The thresholds for the Year 3, 4, 5 tests will be shown in MERiT.

Population data will be available once sufficient schools have entered data for each test each year. This is not based on an absolute number of pupils; it is based on how stable the data is as more schools enter the data. However, it is unlikely that the population data will be based on fewer than several thousand pupils.
