What assessment tool is frequently used to identify learning disabilities?

The ability-achievement discrepancy model is frequently used to identify learning disabilities because it directly compares a student's cognitive abilities, often measured by IQ tests, to their actual academic performance in areas such as reading, writing, or mathematics. This model helps to determine whether a significant gap exists between a student’s potential (as indicated by their abilities) and their actual achievements. A discrepancy suggests that a learning disability may be present, signaling a need for specific educational interventions and support.

The other assessment tools serve different purposes. Multi-factored assessments typically involve a variety of data sources and types of evaluations, including but not limited to triangulating information about a student's academic, behavioral, and social aspects. Standardized norm-referenced tests measure students' performance against a broader population but do not specifically target discrepancies between ability and achievement. Intelligence quotient assessments measure cognitive capabilities but do not provide a full picture of academic performance, making them less effective on their own for identifying learning disabilities.
