South Carolina Unlimited Building Contractor Exam Prep Course

The South Carolina Unlimited Building Contractor Exam is also commonly referred to as the National NASCLA Exam for Commercial General Building Contractors. The NASCLA Accredited Examination Program was designed to assist contractors who need to be licensed in multiple jurisdictions. Contractors who take the accredited examination can access NASCLA’s Examination Database (NED) and request that their results be sent to other jurisdictions accepting the examination, reducing redundant licensing requirements. South Carolina is an administering state for the National NASCLA Commercial Builder Exam.

The NASCLA Accredited exam is recognized as a trade exam for commercial contractor licenses in Alabama, Arizona, Arkansas, Florida, Georgia, Louisiana, Mississippi, Nevada, New Mexico, North Carolina, Oregon, South Carolina, Tennessee, Utah, Virginia, West Virginia & the Virgin Islands.

Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, Oregon, South Carolina, the US Virgin Islands, Utah, and West Virginia also accept the NASCLA exam for licenses that include residential construction.

"I Recommend Using The Services Of Contractor Training Center If You Are Serious About Passing The Exam. "

They don't waste your time with fluff. They arm you with all the right tools and give you special insights that you just won't get anywhere else. I would definitely choose them again if I have any future test requirements.
