California maintains specific C classifications for specialized construction. The requested classification must match the trade experience and the work the business will contract to perform.

Before applying

  • Read the current statutory scope.
  • Map the four-year experience claim to the classification.
  • Open the current trade study guide and topic weights.
  • Check whether reciprocity, NASCLA, or a recent-exam waiver applies.
  • Do not use a broader-sounding classification as a substitute for the correct scope.
