how long does it take to become a tech sergeant in the air force
Technical sergeant Within air force enlisted ranks, promotion to technical sergeant has historically been the second-most difficult rank to achieve[citation needed] (only the rank of senior master sergeant, capped by federal law, has lower promotion rates[citation needed]) and is the most difficult promotion that most career air force members achieve[citation needed]. A staff sergeant must have served at least 23 months in grade to be considered for promotion to technical sergeant[citation needed]. It normally takes 10â€“12 total years of service to attain this pay grade[citation needed]. Technical sergeants mentor junior enlisted personnel while preparing themselves for promotion to master sergeant, the entry rank of the senior non-commissioned grades.[citation needed]

Operate and maintain (organizational and Intermediate level) marine boilers, pumps, forced draft blowers, and heat exchangers; perform tests, transfers, and inventory of lubricating oils, fuels, and water. Maintain records and reports, and may perform duties in the generation and stowage of industrial gases." Enlistees are taught the fundamentals of this rating through on-the-job training or formal Navy schooling. Advanced technical and operational training is available in this rating during later stages of career development.[1]
