 Others, such as the website Mathematically Correct, questioned the NCTM standards approach to teaching mathematics from 1997 to 2003.Some state standards have been criticized for either not being specific as to academic content, or not implementing curricula which follow the new standards.Advocates of traditional education believe it is not realistic to expect all students to perform at the same level as the best students, nor to punish students simply because they do not perform as well as the most academically talented.
