Missouri exam questions
Can I take the 2017 version instead of 2020? Yes. Pick the exam name that ends in 2017 when you book. Taking a 2020 version? Use JCR’s Missouri 2020 NEC package.
Which exam do I need? Your licensing office decides. For the statewide exams that is OSEC. For the others, call St. Louis County at (314) 615-4591 or Springfield Building Development Services at (417) 864-2059.
Can I test from home? Yes for Prov. Its Missouri and St. Louis County exams run at Prov test centers or online with a remote proctor (Examroom.ai). Springfield’s ICC exams run at Pearson VUE.
What about the NASCLA exam through PSI? Missouri’s PSI bulletin lists the 2020 or 2023 NEC for it, so this 2017 package is not the right fit. The Missouri 2020 NEC package covers it.
Kansas City or another city? Many Missouri cities run their own exams. Check the code edition with your city before you order.
Does self-study earn CE credit? No. This package is exam prep only.

If you need to complete your required hours to maintain your electrical license, this course is an excellent choice. Victor Ring kept the class upbeat, engaging, and easy to follow. He does a great job breaking down the material and showing simpler, more efficient ways to navigate the NEC Code book, which makes the information practical and immediately useful in the field. Highly recommend this course to any electrician looking for a professional, informative, and enjoyable way to get their continuing education hours completed.

I have been using JCR Productions for more than a decade and am never disappointed. Victor is bringing some fresh trainings that apply directly to someone that owns their own electrical business.

I have been going to JCR for my North Carolina license continuing education since 2001 and this class has always kept me on top of the code changes and a refresher of all the material in the code book. I have gone to other continuing education classes for licenses in other states and JCR has always been my favorite.
