Gov. Phil Murphy on Friday signed a bill doing away with a $191,584 cap on school superintendent salaries in New Jersey, killing one of former Gov. Chris Christie’s most controversial education policies.

The law bars the state Department of Education from setting maximum salaries for superintendents while, at the same time, setting guidelines for school executive contracts to limit or standardize bonuses, golden parachutes and other fringe benefits.

Christie, a Republican, in 2011 implemented a $175,000 cap on superintendents, citing high salaries and generous perks in superintendent contracts. In the wake of that action, several high-profile superintendents resigned rather than accept a pay cut. Some districts were left with a revolving door of interim superintendents before finding a qualified long-term replacement.

Christie’s administration raised the maximum base pay to $191,584 in 2017 with incentives to earn more if school chiefs stay in the same district.

The average salary for New Jersey school superintendents was $155,631 in the 2017-18 school year, according to an NJ Advance Media analysis of state data. More than 30 collected more than $200,000 in base pay, despite the salary cap that made exceptions for charter schools, districts with career and technical schools, schools for special education students and districts with more than 10,000 students.

Superintendents subject to the cap were also eligible for extra pay if they had a high school in their district, stayed in the same district for multiple contracts or met goals for merit pay.

The law Murphy, a Democrat who succeeded Christie, signed Friday also takes steps to crack down on contract perks, saying no contract can include provisions that reimburse or compensate executives for their legally mandated taxes, life insurance, health care or pension payments.

It would limit severance pay to the lesser of either 12 months pay — at a rate of three months for every year left on the contract — or the remaining salary due per the contract.

And it places restrictions on merit bonuses, specifying that bonuses tied to quantitative goals cannot exceed 3.33 percent and those tied to qualitative goals cannot exceed 2.5 percent.

Superintendents also would not be eligible for monthly allowances other than a “reasonable” car allowances, and “no contract shall include a provision of a dedicated driver or chauffeur,” according to the bill

The state Senate passed the bill (S692) 27-8, and the state Assembly voted 50-19 with five abstentions.
