They can elect to take either the NASCLA Accredited Trade Examination for Electrical Contractors or the AZ ROC Electrical (Commercial) exam. There are differences in these exams. See the PSI CIB for each exam to compare the differences and determine which exam best fits your business needs.
The NASCLA Accredited Examination Program was designed to assist contractors who wish to be licensed in multiple jurisdictions by offering a streamlined test taking option for the trade portion of the contractor examination. Candidates who take and pass the NASCLA Accredited Examination can access NASCLA’s National Examination Database (NED) located on https://ned.nascla.org to electronically send their transcripts to jurisdictions that accept the examination in lieu of their state specific trade portion, thereby reducing redundant licensing requirements. Candidates are expected to follow individual state agency applications to become licensed, in addition to taking a business and law examination, etc. If you are unsure if this examination will meet your specific license requirements in a participating state agency, please contact the state agency directly to confirm. A complete list of participating state agencies can be found on NASCLA’s website by visiting: www.nascla.org.
