Achievement measures reading (sight-word recognition, decoding, comprehension, fluency rate), math (computation, concepts, word problems, automaticity of basic math facts), writing (spelling, written expression, rate of formulating written sentences), oral expression (vocabulary, repeating stories), and listening comprehension (following oral directions).

A learning disability is considered when a child's performance in an area of academic achievement is significantly below his/her intellectual ability; in other words, the child demonstrates solid reasoning and potential, but is struggling to achieve academic success. Therefore, both an IQ test and Achievement tests are administered to assist with determining discrepancies.

Examples of Achievement Tests:

Woodcock-Johnson Tests of Achievement–III

Kaufman Test of Educational Achievement–3

Test of Written Language–4 (TOWL-4)

Standardized Reading Inventory–2 (SRI-2)

Gray Oral Reading Test–5 (GORT-5)
