Question: Historically, each of these tests have been proven to have reliable and valid results, across varying age ranges. The Stanford Benet, intellectual test, the Wessler scales, the Kaufman battery, and the Woodcock John test of cognitive abilities are well respected forms of assessment within the psychological field. Achievement test batteries assess knowledge in broad content areas; each subtest in a battery contains a fairly limited number of items, which restricts their value for identifying students with serious learning problems (Drummond, 2017). Drummond, 2017 continues to explain that similar to achievement test batteries, individual achievement tests cover several broad academic areas as well. Similarly most are designed for a wide age span, usually adolescent to geriatric. Like the Wechsler Intelligence Scale for Children (WISC-IV), the The Woodcock-Johnson III Tests of Achievement were developed with companion instruments (Drummond, 2017). Need Assignment Help?
