This Candidate Information provides you with information about the examination and application process for Contractors Licensure in the State of Oklahoma. Eligibility for examination is determined by the State of Oklahoma.  

STATE SCORE REPORTING

Your score will be given to you immediately following completion of the examination. The following summary describes the score reporting process: On screen – your score will appear immediately on the computer screen. This will happen automatically at the end of the time allowed for the examination. If you pass, you will immediately receive a successful notification.

TIPS FOR PREPARING FOR YOUR LICENSE EXAMINATION  

1.    Read study materials that cover all the topics in the content outline.

2.    Take notes on what you study. Putting information in writing helps you commit it to memory and it is also an excellent business practice. Discuss new terms or concepts as frequently as you can with colleagues. This will test your understanding and reinforce ideas.

3.    Your studies will be most effective if you study frequently, for periods of about 45 to 60 minutes. Concentration tends to wander when you study for longer periods of time. 

STATE EXAMINATION REFERENCE MATERIAL AND CONTENT OUTLINE  

Note: State suggests candidates read all reference materials , before taking the State Exam.   

Contractor School Online (CSO) may be able to assist you with study materials. Do not just rely on(CSO) practice tests, we also suggest candidates to read state reference materials, but our practice test will help you know your weak areas.  

If a test question answer could differ because of conflicting information in test reference sources, a legal requirement such as code, law, or regulation overrides any other reference. If two legal requirements appear to conflict, the state-specific code, law, or regulation overrides the national one.
