Disclaimer: These pages are meant to help individuals, parents and teachers possibly identify potential problems. All these tests are experimental tests. The tests are not definitive, nor legally official. Unfortunately, common Ishihara dot tests are not very accurate either, nor do they explain much at all, and more accurate tests are hard to find. See professionals for more official tests. --- S. Holland
