The requirement that home schooled students score at or above the 40th percentile on a nationally standardized test runs counter to several widely accepted principles of measurement. A single score should not be used alone in decision making, and there is no evidence that this is a valid use of the test. In addition, the 40th percentile is not an appropriate demarcation point for typical, or "normal," performance. A review of the way in which norm-referenced tests are developed confirms that such a requirement is not appropriate. If a set passing score is desired, the fourth stanine is widely accepted demarcation for typical or normal. The use of Virginia or school district norms that are no more than 5 years old is suggested as an alternative to national norms. In addition, superintendents should be urged to consider information in addition to test scores when making a home school judgment. Virginia should encourage superintendents to consider portfolios as an additional assessment option. These suggestions are consistent with widely accepted measurement practices, and will serve better than the language as it stands. (SLD)
