- Chapters must have student members to affiliate with TSA.
- Chapter membership type (Red CAP, White CAP or Blue CAP) must be the same at both the state and national levels.
- A student may belong to only one local chapter and to only one state TSA delegation.
- TSA membership must be affiliated through a local state-registered education district. "Home-schooled" students may only become members through an agreement with one affiliated chapter.
- Advisors of TSA chapters must be registered state-certified educators working in existing school facilities. It is recommended that a science, technology, engineering or mathematics teacher serve as a TSA chapter advisor. However, some other state-certified educator may be appointed by the school’s principal. The appointed advisor has the same rights and privileges of any advisor as long as s/he maintains the chapter in good standing.
- The chapter level (middle school or high school) is designated by the chapter advisor when affiliating each year.
- Two schools may not combine to form one chapter at the same level or different levels. Each school must have a separate affiliated chapter.
- A member may only belong to a TSA chapter where he or she attends school, unless they are home-schooled (per the policy in #4 above).
