You obviously have no clue about CA geography, school enrollment policies or CIF rules.
Number one, those other schools are NOT part of the Conejo Valley School District. The high schools that make up CVSD are Newbury Park, Thousand Oaks and Westlake. Simil Valley, Santa Clarita, Calabasas, Oxnard, etc are not part of the Conejo Valley School District.
Number two, most schools in The Conejo Valley School district have open enrollment, meaning anyone can apply to transfer to one of their schools and as long as they are not impacted, the school will grant a transfer (either inter or intra district). There are no rules being broken by applying to and attending a school outside of your school or district boundary as long as you don’t lie about or forge a residency.
Number three, where rules could be broken and accusations have been made, is around undue influence. Does the coach, runners, families of runners or anyone else associated with the program have contact with and influence enrollment of any of those transfers?
