ASVAB SC Score
Surveillance & Communications
What SC Measures
SC covers signals, surveillance, and communications MOS that require both verbal and technical aptitude. It's a bridge between the language-heavy GT and the math-heavy ST — you need solid verbal ability AND strong quantitative skills. SC jobs typically involve operating and maintaining communications equipment, collecting and analyzing surveillance data, and coordinating operations across units.
Communications work requires you to understand written orders precisely (VE), perform calculations for frequency planning and signal analysis (AR + MK), and visualize the mechanical operation of radio systems and antennas (MC).

How to Improve Your SC Score
Subtests ranked by impact on your SC score. Improving the top-ranked subtest first maximizes cross-composite benefit.
VE is in SC formula — every WK point also improves GT and other VE-dependent scores.
Signal math, frequency calculations, electronics. MK feeds ST, EL, GM.
Word-problem arithmetic. AR feeds GT, EL, FA, CO.
Understanding how radio systems, antennas, and mechanical assemblies work.
