  1. Hi, just finished due process, however school states that as long as child maintained a standard score in the same range from three years ago until now, that they have made progress. If that is the case, why would a child with a standard score of 81 be average in grade 4,,,and a standard score of 81 be below average in grade 7, any help would be great
