The PASS Test was developed specifically for home schoolers. It has certain similarities to other achievement tests in that it estimates student achievement in the subjects of reading, language, and math. But is has important differences. It introduces four major improvements over most achievement tests presently available. First, it was designed for parents to administer at home. This can greatly reduce the stress level of testing. Second, it is untimed, which helps students to relax. Third, the student's approximate achievement level within his or her grade is initially identified by use of a brief accompanying placement test. This assigns each child to a test level where he or she is more likely to succeed, and it also allows for shorter tests. Finally, testing results show overall achievement as well as performance in each subject. The test is standardized and children's scores are compared with both national and home-schooling populations. This does not mean that the test is nationally normed, but that the scores are equated to those of public school students taking one of the nationally-normed tests. The states of Alaska, New York, and North Carolina have officially approved the PASS Test for purposes of state reporting. In other states which require testing, you should check with your local school district to make sure it meets their requirements.
