Construction Supervisors License

This is where GBCC started, teaching Contractors to understand the code book and assist them in passing the Unrestricted Construction Supervisors License Exam.  It turned out to be the beginning of our school.  Now, there are many different books that make up the Building Code.

We are one of the only schools in Massachusetts that will provide you with computer based practice exams.  It only makes sense.  If you are going to take your exam on a computer, you should practice on a computer.

Our philosophy is much different than most schools.

  • No memorization
  • No reading the code books
  • We provide is a complete understanding of how to navigate each book and teach unique indexing strategies.
  • The application and test taking strategies are discussed in detail.
  • Our courses are interactive.  You don't just listen to the instructor lecturing for 2 hours.  Interaction and real life examples to each question is the key to learning, so be prepared to get involved.
  • Our CSL course is six (6) weeks long.  We meet once a week at 6:00 pm.  Class runs until about 8:00 pm. 
  • When finished, you will not only be able to pass the exam but more importantly, you will be able to apply the information to the job site. 
  • We understand that most of our students have not been in a classroom for a long time.  You will be surprised that learning can be fun and informative at the same time.

To be eligible to take the CSL Exam, you must:

  • Be at least 18 years old.
  • Have at least three years of experience.
  • Provide documentation of your experience or provide three years of W2 statements.
  • Have a Social Security number or Tax Identification Number (TIN)

We will discuss what qualifies as experience and documentation in detail during your course.  You will be completely ready to sit for your exam when we are finished!
