What the IPEDS & College Scorecard Data Shows for Environmental Control Technologies/Technicians
Environmental Control Technologies/Technicians is tracked across 288 U.S. postsecondary institutions in the College Scorecard field-of-study file, which links CIP code classifications from IPEDS to Treasury earnings records. This profile covers the certificate credential level specifically, because the Department of Education reports program-level outcomes separately for associate, bachelor’s, master’s, and doctoral awards. The CIP (Classification of Instructional Programs) taxonomy lets analysts roll up specialties into broader families, which is why earnings medians across schools can be compared on a common basis.
Across all reporting institutions, the mean of school-level medians is $47,897, calculated from 66 schools with published earnings data. The earnings distribution stretches from $23,876 at the low end to $69,072 at the top, with a 25th-75th percentile band between $42,738 and $55,887 around a median of $45,679. The top-reporting institution in this program is Ranken Technical College at $69,072. These numbers reflect Treasury-derived wages, deferred compensation, and positive self-employment earnings four years after completion for federally aided completers who were working and not enrolled.
Variation across schools matters more than a single national figure. Completer counts and earnings cohort counts are distinct source fields, so the displayed completer count should not be assumed to be the earnings denominator. PlainCollege's debt-to-earnings ratio divides median federal debt by annual median earnings as a descriptive comparison; it is not the Department's formal gainful-employment test. Use the school-by-school table to compare reported outcomes while accounting for cohort size, suppression, program mix, and location.
Northwestern Technological Institute accounts for 11.9% of all Environmental Control Technologies/Technicians certificate credential graduates
That concentration — well above the 5% national median for largest-entity share means Environmental Control Technologies/Technicians-wide averages can mask meaningful variation outside the largest entity, though the remaining entities individually still carry a share worth reading on their own. That school produced 577 graduates in the most recent cohort, anchoring a meaningful slice of national supply for this field. Even a notable-but-not-dominant share like this is enough to skew a simple Environmental Control Technologies/Technicians-wide average away from what a typical smaller entity looks like.
Environmental Control Technologies/Technicians certificate credential median earnings varies 2.9× across entities
Environmental Control Technologies/Technicians certificate credential median earnings ranges from $23,876 (lowest) to $69,072 (highest), a spread of $45,196. That spread reflects typical sectoral variation between selective research institutions and broader access institutions. Earnings are measured four years after completion using Treasury-derived records for federally aided completers who were working and not enrolled. They are descriptive early-career outcomes, not forecasts of longer-term earnings.
Environmental Control Technologies/Technicians certificate credential median debt varies 2.2× across entities
Environmental Control Technologies/Technicians certificate credential median debt ranges from $6,333 (lowest) to $14,069 (highest), a spread of $7,736. That spread reflects typical institutional cost differences, public in-state, public out-of-state, and private school financing models produce predictable spreads. Median debt counts only those students who borrowed federal loans, students who paid out-of-pocket or received institutional grants are excluded from the borrower median, which can flatter low-debt schools.
Environmental Control Technologies/Technicians debt-to-earnings ratio is 0.23 — well below typical (typically associated with unusually small scale or exceptionally high per-unit investment)
debt-to-earnings ratio is the simplest comparative metric but it does not capture the full picture: this ratio uses federal loan principal, not all education debt, private loans, parent PLUS loans not in the borrower’s name, and institutional debt are excluded Values this far below typical often correlate with unusually small scale or population characteristics rather than higher resource budgets per se — worth checking whether the underlying denominator is itself an outlier.
Earnings trajectory. For the 60 schools reporting both horizons, median earnings are
46% higher four years after completion than one year
after. That is the same graduates measured twice, not two different groups, so it
describes how pay develops early in the career rather than a difference between schools.
A school missing from this count reports only one horizon.
Awards and earnings come from different reference periods, so they are not a count and an
average of the same people. Awards is the number of credentials the school reported for the
latest IPEDS year; median earnings is measured four years after completion, for a separate
pooled cohort of earlier graduates. A school can therefore report zero awards in the latest
year and still have earnings on record. The earnings figure is not the awards figure’s
average, and the awards count is not the earnings sample size. Schools are ranked on the
four-year earnings figure only, so every row is compared on the same basis.

Peers exclude the same two-digit CIP family so neighborhoods are not CIP-containment siblings.
School-count peers include Ground Transportation, Building/Construction Finishing, Management, and Inspection, Heavy/Industrial Equipment Maintenance Technologies/Technicians. Earnings peers include Precision Metal Working, Liberal Arts and Sciences, General Studies and Humanities, Heating, Air Conditioning, Ventilation and Refrigeration Maintenance Technology/Technician (HAC, HACR, HVAC, HVACR).

Earnings data comes from the U.S. Department of Education College Scorecard Field of Study file retrieved in March 2026. The program metric displayed here represents federally aided completers who were working and not enrolled four years after credential completion, using Treasury-derived records published through the Scorecard. Completer counts and debt figures come from the same field-of-study snapshot; the Department refreshes components on schedules documented in its changelog, not one fixed annual date.
