Tests that are intended to discover whether a child has the necessary skills and development to benefit fully from instruction, as in reading readiness tests. Sometimes mistakenly confused with developmental screening tests, which focus on a child’s ability to learn, readiness tests instead focus on whether the child has acquired skills needed for more advanced learning. Doing poorly on a readiness test may mean that a child has not had experience or teaching at home, not necessarily that the child has a learning problem (of the type developmental screening tests are supposed to identify). Examples of widely used readiness tests are California Achievement Test, Metropolitan Readiness Test, Boehm Test of Basic Concepts, and Brigance Inventory of Early Development. Such tests are widely used for class placement and curriculum planning for children, even though current research indicates that tests for young children are notorious for having very poor reliability and validity because children change so fast and grow at such individual and varying rates.
