The empiricist/environmental theory focuses on the external evidence of learning,
in particular, knowing colors, shapes, ones address, and how to spell ones name,
counting to ten, letters of the alphabet, and behaving in an appropriate manner. Children
learn these skills through the teaching environment. The empiricist theorists also use
readiness tests. The most popular tests are the Comprehensive Tests of Basic Skills,
California Achievement Test, and the Stanford Early School Achievement Test.
