The WASI–II, a revision of the WASI, is a quick, reliable measure of intelligence for use in clinical, educational, and research settings. The WASI-II revision maintains the format and structure of the WASI and provides greater clinical utility and efficiency by offering new content and improvements. Building on the WASI, the WASI–II provides updated versions of the WASI Vocabulary, Similarities, Block Design and Matrix Reasoning subtests; four- or two-subtest administration versions; and strengthened connections with both the WISC®– IV and WAIS®–IV.
