Achieving dual certification would require paying dues to both entities. Between NAR and
Tripoli the primary differences are: NAR tends to focus more on model rockery and contests. It appeals to children, scouting groups and novelty launches like hang-time and egg tosses. Tripoli's focus is geared more toward higher power, experimental and advanced rocketry. Tripoli for example encourages experimental (EX) or ammonium-perchlorate based non-commercial individually manufactured rocket motors for Level 2 and above certified fliers as well as hybrid motors (for example nitrous oxide gaseous oxidizer and solid rubber fuel). Tripoli also has active mentoring programs with many engineering programs of US universities and as above supports the exploration of the hard science of and limitations of rocketry by educated private citizens including class-3 rocketry. The non-NASA private spaceflight companies are launching what are classified as Class 3 rockets and above. At least one current employee of Space-X obtained his experience flying high powered rockets with the Tripoli Houston prefecture of the national organization as a university student enrolled in the engineering program of a local university.

sized rocket and retrieve it successfully in a condition suitable to launch it again safely. This is also true for Level 2 and 3 certification with the added requirements that, for Level 2 a written test be successfully passed and for Level 3 the build be documented and overseen by two designated technical authorities called TAPs (Technical
Advisory Panel) who are themselves Level 3 certified and notably proficient at rocketry. The level 3 technical authorities are authorized by the respective Tripoli or NAR national organizations. These requirements vary slightly between NAR and Tripoli, but are very close in both organizations.
