Analysis
A debt-to-earnings ratio of 0.27 represents one of the more manageable financial pictures in career training. Based on comparable plumbing programs nationally, graduates typically earn around $35,000 in their first year while carrying roughly $9,500 in debt—meaning the credential could pay for itself in less than four months of full-time work. For a trades certificate that gets someone working quickly, these are encouraging fundamentals. The challenge is that New Jersey's plumbing market appears tougher than the national average, with similar programs in the state producing median first-year earnings around $28,000. That's a meaningful gap.
What makes this estimate particularly uncertain is the limited number of comparable programs—only 17 nationally for earnings and 7 for debt. With so few data points, individual program outcomes can vary significantly from these benchmarks. The two other plumbing schools in New Jersey with reported data show first-year earnings ranging from $25,000 to $30,000, suggesting considerable variation even within the state. For a family considering this path, the key question becomes whether National Career Institute's connections to local employers can deliver outcomes closer to the national norm than the state median. Given the relatively low debt burden, the financial risk is contained even if earnings fall short of estimates, but the program's value depends heavily on job placement support that data alone can't measure.

Earnings: Median earnings from IRS W-2 data for graduates who are employed and not enrolled in further education, measured 1 year after completion. Earnings are pre-tax and include wages, salaries, and self-employment income.
Debt: Median cumulative federal loan debt at graduation. Does not include private loans or Parent PLUS loans borrowed on behalf of students.
Estimated Earnings: Actual earnings data is not available for this program (typically due to privacy thresholds when fewer than 30 graduates reported earnings). The estimate shown is based on the national median of 17 similar programs. Actual outcomes may vary.
