How this guide is sourced and reviewed
Wages (BLS): All median and percentile figures are BLS OEWS May 2025, SOC 49-2095 (relay technicians) and the matching SOC codes for each comparison role. OEWS is sampled on a rolling 3-year basis and published ~10 months after collection, so treat it as a firm anchor rather than a spot rate.
Job growth: Projected 2024–34 employment change, and the average annual openings figure, are from the BLS Employment Projections program, by occupation. Openings are a per-year average over the projection decade, not a decade total.
Licensing & credentials:Requirements are drawn from the issuing state licensing boards and the certifying body behind each credential — not from third-party aggregators.
Demand signal:Any statement about how quickly this role clears offers reflects GlobalCybers placement request volume across the trailing 12 months — our own network data, offered as a directional real-world indicator alongside BLS, not a market-wide survey.
