Middle School and High School Online Challenges

I was recently thinking abut this while working my team’s website for the Online Chanllenge. Are middle school and high school Online Challenges separated so that their is a middle school winner and a high school winner, or is a hybrid of both age groups? Thanks in advance.

Each challenge has its own eligibility requirements, and every challenge is a single contest with all entrants judged in comparison to all other entrants, regardless of grade level. There is no single challenge that will give multiple awards to different grade level. (The Promote Award is divided into VRC and VEX IQ Challenge contests – but those are separate challenges.)
