TRENTON, N.J. – The New Jersey Taxpayers Guide to Education Spending 2017 is revealing some interesting information about how the state’s schools spend tax dollars, including a wide range for teacher and administrator salaries, as well as per-pupil spending.

The taxpayer guide, published by the New Jersey Department of Education in April, shows median salaries for teachers ranged from a low of $43,911 in the East Newark Borough district to a high of $105,650 at Northern Valley schools, NJ.com reports.

The top 50 school districts in the state pay educators a median salary of at least $78,000.

The data, from the 2015-16 and 2016-17 school years, shows a large spread in median pay for administrators and support staff, as well.

In the 470-student Franklin district, for example, the median administrator pay was $167,127 in 2015-16, while the median Ridge and Valley CS administrator took home $42,637 the same year, the New Jersey Herald reports.

Median support service pay in Wallkill Valley was $91,775 in 2016-17, compared to a median of $37,392 in the Redon district that year.

Part of the discrepancy is due to the fact that different state bureaucrats measure the metrics differently, Kittatinny superintendent Craig Hutcheson told the New Jersey Herald, which makes it difficult for parents and taxpayers to track what’s going on.

“The average person doesn’t understand,” he said, adding that the salary calculation “shifts from (state) administration to administration.

“There’s so many different factors which go into the calculations,” he said.

The same goes for per-pupil spending, which also varies widely because of things like transportation costs, which are virtually zero in urban districts where students walk to school but quite expensive in rural areas with long bus routes.

The Ridgewood Patch points out that the Taxpayers Guide shows per-pupil spending in 2015-16 ranged from a high of $97,424 per student in the Bergen County Special Service district, to a low of $10,181 in the Jersey City Global CS district.

According to the news site:

These costs include: transportation, special revenues, pension and benefits paid by the state, facilities (including debt service), equipment, total food services, judgments against the school district and tuition/costs for students sent out of district (except payments to charter schools), according to state officials.

School spending per pupil for 2015-2016 was $14,939, a 2 percent increase over the year before. The data also counts the overall costs to districts, including pensions and transportation costs that are unique to each district and many of which borne by the state, according to NJ Spotlight.
