2026 TWS Training Schedule

2026 Training Schedule for Tribal Water and Wastewater Utilities Personnel
The ITCA National Tribal Water Systems Operator Certification Program is pleased to provide this schedule of free operator training and certification events (see below Table of Events). The table will be periodically updated as new training courses are confirmed. When a course is open for registration, its title is shown in the table with an active link. Click on the active course title in the table for details and registration instructions. Events that have already occurred are shown in gray with a strike-through. Events that are not yet open for registration are shown in black and don’t have active links. Some courses are offered more than once to provide operators with options. Instructors may vary from one course offering to another.

Types of Course Formats

  • Online Courses. Some courses are offered in a 100% live online virtual format. (Note: certification exams are available year-round through computer-based testing.)
  • In-Person Courses. Some short-duration, continuing education training events may be offered in a 100% in-person format. Some courses will include in-person certification exam sessions.
  • Blended Courses. Comprehensive, certification preparation courses are offered in a Blended format, which consists of two sequential parts: (Part 1 uses live online virtual format) + (Part 2 uses in-person classroom format).

The in-person Part 2 picks up where the virtual Part 1 ends. The in-person Part 2 will not reviewing curriculum content covered during the virtual Part 1. For certification preparation courses that are in the blended format, the in-person Part 2 includes in-person certification exam sessions.

Training Contact Hours All ITCA Program training events provide opportunity for students to earn training contact hours based on participation and attendance. The terms “lesson”, “class”, and “course” are defined in the ITCA Standards for Contact Hour Credit from Virtual Training Events document.

Certified Exams

  • Computer-Based Testing. Certification exams are available year-round through computer-based testing (CBT) at over 300 nationwide testing center locations (See 2025 CBT announcement).
  • Paper-Booklet Testing. In-person certification exam sessions using paper-booklet testing (PBT) are included during Blended certification preparation courses. In addition, the ITCA Program may periodically offer stand-alone, in-person PBT exam sessions.

Travel Expense Reimbursement Participant travel expense reimbursement stipends are available for participants of the in-person parts of ITCA Program training and certification events. For more information, contact the ITCA Tribal Water Systems Program by phone at (602) 258-4822, or by email at TWSInfo@itcaonline.com. *Specified Regional or Area Designations Most of the online training courses are listed without any specified region or area and are therefore, open without restriction. However, some training courses are listed for certain regions or areas. Such training courses are made possible by funding agencies for the express purpose of serving certain geographic areas. When a course is listed for a specific region or area, two different registration options are available—Priority Registration, and General Admission Waiting List.

  • Priority Registration

If you work on Tribal lands in the region or area specified for that course, please use the “priority registration” option. Priority registration will be monitored and tracked based on the work address provided during registration.

  • General Admission Waiting List

Online training course size is limited to preserve the high quality of student-focused instruction. A general admission waiting list is available for personnel working on Tribal lands that are outside of the region or area specified for the particular course. Selection for the course will be first come, first served based on seats available after the priority registration seats are filled. IHS Area Map, below
