All trainee teachers hoping to gain Qualified Teacher Status (QTS) need to pass a computerised numeracy skills test. The test is designed to ensure they have a sound grasp of numeracy skills such as mental arithmetic and interpreting statistics, and can apply these in their work. This book outlines the test requirements and explains the essential subject knowledge needed. Fully updated to comply with the TDA standards, this edition also includes a glossary and suggestions for further reading. At least 100 practice questions and answers enable trainees to prepare to complete their test confidently and successfully.
