Yes. Both Training Certificates of Completion and the Certification require annual maintenance. Level I TCOC or the BOC Certification require 5 maintenance points a year and a $75 application fee . The Level II TCOC requires 10 maintenance points and a $75 application fee. Information will be emailed and mailed to you from NEEC the January of the year you are due for maintenance. If you maintain your Level II credential and also hold a Level I TCOC or Certification, that credential will automatically be renewed with no additional points or fee required. Your credential (TCOC or Certification) is valid for a full calendar year after you earn it.
