Some of our team members are studying Grade 9 at a secondary school (which covers grades 8-12 here). In this case, can you clarify if a 14 year old 9th grader is allowed? They will turn 15 next August.
Unfortunately these students would be ineligible to participate in the VEX IQ Challenge. This is indicated in the definition of a Student in the VEX IQ Challenge Highrise Game Appendix.
There is an exception for 9th graders who are attending a 7-9 Middle School, however this exception does not apply for 9th graders who attend an 8-12 secondary school like yours.
