All of Lexia’s products are designed according to the latest scientific findings in education and interface designs are tested for outcomes in schools. Fifteen scientifically based, peer-reviewed studies evaluating Lexia products have shown their effectiveness with multi-ethnic populations through the United States and the United Kingdom. The use of Lexia software supported achievement gains by study groups that proved to be significantly superior to those achieved by control groups receiving equal amounts of traditional instruction and practice.
