What is Navy A-School and what should you expect?
TL;DR — Quick Answer
A-School is your rating-specific technical training after boot camp. Length varies from 4 weeks to over a year depending on your rate. It teaches the foundational skills for your Navy job and determines your initial duty station.
What A-School actually is
A-School is the Navy's technical training pipeline. After graduating boot camp at Great Lakes, you travel to your A-School location (which varies by rating) and begin learning the specific skills for your job. Some ratings like IT train at Corry Station in Pensacola, while others like HM train at Fort Sam Houston in San Antonio. The rates comparison table shows the A-School length for every rating.
How long does A-School take?
Duration ranges dramatically. Undesignated sailors and some surface ratings have A-Schools as short as 4-6 weeks. Technical ratings like CTN, ET, and Nuclear ratings can be 6 months to over a year. Some ratings also have follow-on C-Schools for specialization. Check the shortest A-School and longest A-School rankings to compare.
Life during A-School
A-School is more structured than college but more relaxed than boot camp. You attend classes during the day, study in the evenings, and typically have weekends off once you earn liberty. Housing is usually barracks-style. Married sailors may receive BAH and live off-base. The academic workload is real: sailors who fail tests can be rolled back, held, or reclassified to a different rating.
What happens after A-School
Upon graduating, you receive orders to your first duty station. This could be a ship, a shore command, a submarine, or an overseas base. Your class ranking and the Navy's needs both factor into which orders you receive. Higher performers generally get first pick. Check the duty stations page to learn about where you might be assigned.

Read article →Why is there no B-School after Navy boot camp?
The Navy originally used an A-B-C-P school alphabet where A meant Apprentice, B meant intermediate Bridge training, C meant Chief-level specialty school, and P meant Preparatory. B-School was phased out during the mid-20th century as the Navy consolidated its training pipeline, and today sailors jump straight from A-School to C-School with no intermediate step.
