I’m a parent of a recent (pre-Covid) out-of-area Parkland student who went on to Poolesville magnet program. For advanced students, the academic program is strong and the 8th period allows them to take language, music, AND one more elective (tech, arts, or science). About half the classes are homogeneous grouping (math, language, science, and de facto music) the others are heterogeneous grouping, but my observation was that kids in the same language and music also ended up together in their English and Social Studies classes due to the schedule. I wouldn’t worry about overall school ratings. The area is generally low SES, which is why the lottery program is there (to draw more high SES to the school).
Since you can always return to your home school, my suggestion is to try it for at least one full year. What I think was most valuable for my kid was learning to work with kids not like them and having access to many clubs and other enrichment. They also learned some independence and how to use public buses to get home (8th grade). It was a nice school with lots of green teachers.
