To register for the NASCLA Commercial Builder Exam, you'll need to:

  • Apply to take the exam with NASCLA by visiting ned.nascla.org.

  • Schedule your exam with PSI. Once your application is approved, you will receive an email with a candidate ID number and a link to schedule your exam. 
  • Pass the five-hour, open-book test consisting of 115 questions. A 70% score is required to pass.

Once you’ve taken and passed the exam, you will receive a score report validating your results. Then:

  • Return to the NASCLA National Examination Database (NED) at ned.nascla.org and create a user account. 
  • Link your score to your profile.  
  • Purchase a transcript to send to the North Carolina Licensing Board for General Contractors (NCLBGC). The transcript fee is $30 per state.

Important Notes:

  • You must be pre-approved by NASCLA before you can take the exam. 
  • Once approved, you are eligible to take the exam for one year and may attempt the exam up to three times within that year. 
  • Transcripts are valid for two years. 
  • Passing the NASCLA exam is just one step in the North Carolina licensing process.
