The document discusses word study techniques for teachers, including a Feature Inventory approach that provides a comprehensive assessment of a student's full word knowledge rather than just their stage of development. The Feature Inventory results in a total score that can track student progress over multiple years and allow comparisons between students. The document also interprets different score ranges on the Feature Inventory, indicating whether a student has a secure understanding, is in a stage of development, or has too much unknown without a firm base of previous understanding.
