Yes, an Armed Forces Qualification Test (AFQT) score of 70 is considered a very good score. It places you in the 70th percentile, meaning you scored as well as or better than 70% of the nationally representative sample of test-takers aged 18-23. This score makes you eligible for enlistment in all branches of the U.S. military and opens the door to a wide range of job opportunities.

What a score of 70 means for your military options:

Maximum Branch Eligibility: You exceed the minimum AFQT score required by every service branch, including the more selective Air Force and Coast Guard.
Access to Most Jobs: Your high score typically results in strong line scores (composite scores in mechanical, administrative, general technical, and electronics areas), which are used to qualify you for specific Military Occupational Specialties (MOS), Air Force Specialty Codes (AFSC), etc.
Potential for Bonuses and Incentives: High scores can make you eligible for enlistment bonuses, guaranteed job training in technical fields, and other incentives offered by recruiters.

Key Limitations:
While excellent, a 70 does not guarantee every single job. The most specialized, highly technical roles (e.g., some cryptography, advanced intelligence, or certain nuclear fields) may require even higher line scores in specific areas. Your physical qualifications, security clearance eligibility, and the current needs of the branch will also determine final job placement.
