Environmental Control Technologies/Technicians at Miller-Motte College-Chattanooga
Undergraduate Certificate or Diploma
Analysis
Miller-Motte College-Chattanooga's environmental control technology program produces earnings that trail the national median by about $3,600 in the first year, but its performance looks different when you zoom in on Tennessee. Among the three schools offering this certificate in the state, this program sits at the median for both earnings and debt—meaning if you're staying in-state, you're not leaving money on the table by choosing Miller-Motte.
The $13,000 debt load represents a reasonable 40% of first-year earnings, and with a robust sample size of 100+ graduates, these numbers reflect actual outcomes rather than statistical noise. The 7% earnings growth to nearly $35,000 by year four shows modest but steady progression. For context, 85% of students here receive Pell grants, suggesting this program serves primarily low-income students who may be trading up from jobs with no credential requirement.
The core question is whether this particular credential opens enough doors to justify the cost. Starting at $32,364 puts graduates above poverty-level wages but below what you'd earn in many skilled trades. If your child is already working in HVAC, water treatment, or related environmental services and needs a credential for advancement, this makes sense. As a starting point with no prior industry connection, the modest earnings suggest exploring whether direct entry into skilled trades might offer better pay without the debt.
