There are 2 models- some schools have 5th switch classes for different subjects or group of subjects to be more like middle school. Others use the traditional model of one class with one teacher for all subjects. Many schools who did switching reverted back to single teacher with Covid for ease of contract tracing last year and the virtual/hybrid year.
Most schools do classroom/homeroom groups. Everyone follows the standards and curriculum set by VDOE. APS has a new math program next year, I think it’s called envision? Not sure yet. Teachers haven’t been trained on anything yet.
APS uses a cluster model for gifted. The gifted teacher is a resource for the teachers and generally does not need provide consistent direct student instruction. They’ll come in here and there for model lessons but there’s only one of the for them whole school. Not enough for regular direct services.
