The document discusses how to effectively use Question Level Analysis (QLA) to analyze student performance on assessments. It explains that QLA involves administering end-of-unit assessments in class, marking them, and inputting student scores into an Excel spreadsheet to calculate data for the whole class and compare performance to other classes. This identifies problem areas to reteach content and skills. The document provides guidance on setting up QLA assessments, including covering a variety of skills and marking the test. It demonstrates how the Excel sheet can track individual student and class progress. Teachers can then use the analysis to plan targeted revisions and address weaknesses before the next assessment.
