The State of New Jersey allows individuals who fail specific sections of the NJ Master Plumber Test to retake only those sections over, rather than retaking the entire test,

after a six month waiting period.

​

North Star Educational offers those individuals the opportunity to study for only the sections of the test they need to retake, at a reduced rate. 

​

In addition, individuals can opt to take just the four-hour refresher section of the course, also at a reduced rate.
