Excellent question. Typically, you want to mention those things on the application. When my two young adults were in high school I assisted them with creating a one (1) page "BIO on their accomplishments over the years (9 - 12 grade); similar to a resume". It included everything they were involved in academically, sports, travel abroad, volunteerism, church, etc. They used that bio to "attach to their college application and interviews". Interviewers were highly impressed.
FYI, my son is a recent medical school graduate (5/2018), 1st year Resident Pediatrician; and, daughter 1st year Accelerated Math High School Teacher (5/2018).
They shared their "bio template" with family & friends, which are experiencing success with documenting accomplishments.
Good Luck to You!
