I'd imagine it's school by school. My son was at the Taft AC where they initially said you were guranteed admission to Taft if you were at the AC but the reality seemed different - more like you might be guranteed admission to Taft high school - not necessarily the IB program.... but then again, it seems like the rules change if your child makes an application to another high school. I know Lane and Whitney's programs are six year programs and admission is guranteed to high school. Was at Whitney's curriculum night last night and didn't hear anything about any changes.
