School Districts are definitely agencies under New York State law.
"Do I contact the Committee on Open Government to get public records?
No, the Committee does not maintain records generally. To obtain records, you must contact the agency that you believe maintains possession
of the records. For example, if you are interested in obtaining minutes of a school board meeting, your request should be made to the school district."
You should be successful in obtaining this information as well, since your request pertains to a record that they would have, and since you are requesting that any and all identifying information regarding particular scores is redacted, it wouldn't violate any of the other children's right to privacy.
Also, to clarify, you don't actually need to determine who the Records Access Officer is prior to making the request. It is sufficient to write the request to the 'Records Access Officer' of the School District, without writing that person's particular name.
I hope the above information is helpful.
