The ABLE kit has been designed to provide classroom teachers with a reliable, evidence-based assessment tool that will enable them to identify readers with reading difficulties as well as the specific basic literacy skills that may be the source of that difficulty. The kit comprises two tests: a Screening Test to be administered to the whole class and a Diagnostic Test to be administered individually. Administration should take place at the beginning of the fifth grade or at the end of the fourth grade if the same teacher is going to continue teaching the same pupils in the fifth grade.
