Achievement tests are a great way to track academic growth from year to year. The scores provide lots of helpful information for planning your school year without making it necessary for you to absorb it all at once.
These are the five most commonly used achievement tests. Each has a total composite score and subscores. It is recommended that you use the same achievement test each time you test in order to be able to compare the scores. Georgia Homeschool Educators Association (GHEA) has described the tests below.
Iowa Test of Basic Skills (ITBS)
This is a top-rated nationally standardized achievement test designed to evaluate thinking skills. This test takes less time to administer than the Stanford and permits a wider grade range of students to be tested at the same time. This test is considered to be among the most difficult tests. Grades 3-8 may be tested together; grades 9-12 may be tested together. Qualifications for test administration: a 4-year baccalaureate degree in any field. Directions for administration are supplied at no additional cost. Tests are supplied and returned to suppliers for scoring. Tests are given orally through grade 2.

The test administrator must have a baccalaureate degree in any field, plus meet additional test administering guidelines. The publisher of this test has strict guidelines that must be followed when testing any relative. The test supplier can supply you with specifics before ordering the test. Qualifications for test administrators and directions for administration must be purchased.
California Achievement Test (CAT)
