Alis/CEM IBE provides predictive and value-added analysis on a range of post-16 qualifications including A/AS Levels, International Baccalaureate and Pre-U. However, not every qualification for which we collect data will necessarily appear in the predictive or value-added reports. This is because the Alis analysis is derived from the exam results collected for each post-16 qualification each year and the data set for each qualification is analysed separately. Each data set must meet CEM's minimum criteria for publication which includes considerations such as the number of individual exam results received i.e. the number of students represented in the sample, the number of schools represented in the sample and the strength of the statistical correlations. Lists of the qualifications appearing in the reports are produced each year and are available as part of the suite of value-added reports.
