Is this discrimination? I don’t want to cry racism.

Question: who was doing the recommending for placement into the next year honors course? I.e. was it your English teacher, or someone else (e.g. counselors)?

Have to agree here.

Some high schools offer placement in honors courses strictly based on grade in the prior course (e.g. A in prior regular course or B in prior honors course is needed to take the following honors course). Of course, if there is racial (or otherwise undesirable) bias in a teacher’s grading, that can still be a problem, but having it just be based on the prior course grade eliminates any shenanigans or mistakes that an additional referral or recommendation procedure could allow in.
