Actually, in most school districts the scores are only confidential when associated with specific student names. The raw data itself is pretty widely available and is used for a variety of purposes. They are, after all, just numbers; including names with numbers is what requires confidentiality. I know in our small school, if a parent asks, they can be told in which percentile their child scored, or what the child's class rank is- both for the entire class and within each subject, so knowing that your child is #2 in ELA or top 10 in math isn't uncommon. I am pretty sure that Mrs. Gumbo4X4 understands the concept of confidentiality and how it relates to her job security.
Absolutely but the information he says he has is not statistical and public. He claims to know who is above his daughter and the scores.
"DW is a clerk for the district. One of her jobs is to compile the test scores. She doesn't know all the names of all the top scorers from the other elementary school (we have just 2 in our district), but she has inquired into the top scores. DD is consistently top 10 in Math & Science, & #2 in language arts. Another girl is consistently #1 in language and is in a league of her own (that girl's mom is a 6th grade teacher and a really good one). DD is always a pretty big gap behind #1 and then there is another big gap before "all the rest"."
I believe that her job is to compile these scores and "forget them" not share them with her DH.
perhaps another class is full of jocks...that right there would skew the scores. Clearly the group of musicians would usually score higher than the jocks...in general.
