NAR vs Tripoli: Which Rocketry Organization Should You Join?

In the United States, high-power rocketry runs through two national organizations: the National Association of Rocketry (NAR) and the Tripoli Rocketry Association (Tripoli, or TRA). Both let you certify, buy H-class and larger motors, and fly at insured club launches. The question is which card you should carry first.

The short answer: join the organization that launches near you. The longer answer is worth reading before you pick, because dues, insurance, exams, and club culture are not identical.

What Both Organizations Give You

NAR and Tripoli both:

• Offer Level 1, 2, and 3 high-power certification
• Include liability insurance with membership (details differ — see below)
• Run local clubs — NAR sections and Tripoli prefectures
• Recognize each other’s senior high-power certifications (you still need a current membership card)
• Require you to fly certification attempts at a sanctioned launch with a qualified official

You do not need prior certification to join either one. Membership comes first; the L1 flight comes after.

Membership Cost

Tripoli publishes current dues on its membership page. As of this writing:

| Tripoli type | Annual dues | Who it is for | |--------------|-------------|---------------| | Junior | $20 | Under 18 | | Student | $20 | Ages 18–25 with valid student status | | Senior (new) | $70 | Age 18+, first year | | Senior (renewal) | $60 | Age 18+, returning members |

Tripoli’s first-year senior rate is higher because it includes producing and mailing the Member Handbook binder. Junior and student materials are digital. Local prefecture dues and launch fees are not included — those are extra and vary by club.

NAR does not list a public dollar amount on its current join page. You see the live rate during checkout at nar.org. A widely circulated mail-in application listed $70/year for members 26 and older and $30/year for junior, leader, and younger senior categories, with family discounts. Treat those figures as historical, not a quote. Check current pricing when you join. NAR also publishes life-membership rates by age ($1,000 at 65+ up to $2,500 under 55) if you want to pay once.

Insurance

Insurance is why landowners let clubs use fields. It is also why you cannot just fly an H motor in a park.

NAR states that members and sections are covered by $5 million of liability insurance per occurrence (with a $6 million general aggregate to the NAR). The policy has a $5,000 deductible per bodily-injury or property-damage claim; the member is responsible for the first $1,000 on a first claim and the full deductible on later claims in the same policy year. Coverage is for personal, non-business sport rocketry and is void if you violate the NAR safety codes. Details live on NAR’s insurance pages.

Tripoli states that sanctioned events are backed by up to $3,000,000 in primary liability coverage, subject to the policy. Published figures include $25,000 medical payments and a $2,500 member responsibility on property-damage claims. Coverage runs calendar-year and applies to prefecture-hosted events and member activities that follow the Unified Safety Code. Details live on Tripoli’s insurance page.

Neither policy is a blank check. Commercial work, safety-code violations, and (for NAR) alcohol-related activities are excluded. If you are flying at a school or asking a farmer for a field, the club’s insurance certificate is the document that matters — ask the prefect or section before you promise a landowner anything.

Certification: Same Ladder, Shared Credit

| Level | Motors | Typical next step | |-------|--------|-------------------| | L1 | H–I (160.01–640.00 N·s) | First high-power card | | L2 | J–L (640.01–5,120.00 N·s) | Written exam plus a bigger flight | | L3 | M+ (5,120.01+ N·s) | Project review, TAP / L3CC process |

Reciprocity is real for senior certifications. Tripoli will update your TRA level if you email hq@tripoli.org a copy of a current NAR card that shows your certification. NAR honors Tripoli certifications at NAR launches if you show a current Tripoli membership card, and NAR members can grandfather a TRA Level 1 by sending proof to NAR HQ. Junior programs are not the same — NAR Junior HPR and the Tripoli Mentoring Program do not transfer one-for-one.

You still need active membership in the organization whose launch you are flying. A lapsed card means a lapsed privilege, even if you certified last year.

L1 itself is similar in both orgs: build a conventional rocket, fly a single certified H or I motor, recover it in re-flyable condition, and get a witness signature. The fork in the road is Level 2.

The L2 Exams Are Not the Same

L1 has no written exam. L2 does, and the tests differ. Both are now taken online before the flight. Bring the completion certificate to the field.

NAR L2 exam

• 40 multiple-choice questions from a published 100-question pool
• Sections cover regulations (mostly NFPA 1127), motor designations, range and safety practices, and stability
• Passing score: 87% — at least 35 of 40 correct
• As of January 5, 2026, NAR administers the exam online; older in-person written tests are being phased out

Tripoli L2 exam

• Two parts: Part A, 25 technical questions; Part B, 25 Unified Safety Code questions
• You must finish Part A before Part B
• Passing score: 90% on each part — no more than two wrong per 25-question section
• Retakes are allowed after the platform’s cooldown

Launch Culture

This is the part forums argue about, and it is only half true as a stereotype.

NAR is the older organization (1957). Sections often mix model, mid-power, and high-power. You will see more contest flying, education outreach, and family pads next to HPR pads. Sport Rocketry magazine comes with senior membership.

Tripoli (1964) is more tightly identified with high-power. Prefectures are where you will more often find research-motor launches (members flying motors they made, under TRA research rules). HPR Magazine and the Tripoli Report are the house publications. Some of the country’s largest “bring a J, stay all weekend” fields are Tripoli launches.

Plenty of NAR sections fly serious HPR, and plenty of Tripoli prefectures are welcoming first-cert fields. The useful question is who has a waivered field nearby, and how often do they fly?

The hard split is research motors. NAR launches fly certified commercial motors only. Mixing your own propellant later means Tripoli, the right certification, and a research launch. That is not an L1 problem.

Which One Should You Join?

Join the club that will actually put you on a pad. Use the NAR club finder and the Tripoli prefecture finder. Email the club, say you want L1, and ask which membership they need to see.

Practical rules of thumb:

• One local club, one organization — join that organization
• Two clubs, two organizations — join the cheaper one first (often Tripoli senior at $70 new / $60 renew; confirm NAR’s checkout price), then add the second when you are flying both calendars
• No local club — NAR’s larger section map is often the better first search, but check both. Some regions are Tripoli country
• Planning L2 this year — the exams are both doable. Pick the org whose officials will be at your target launch
• Under 18 — read Junior HPR (NAR) and the Mentoring Program (Tripoli) separately. Do not assume adult L1 rules apply

Dual membership is normal, not extravagant, once you are in the hobby. Certify with whichever official is standing on the field. Transfer the level to the other card when you join.
