Water Credit Categories
The February 2024 revision of the Vermont Water Supply Rule requires that Class 2, 3, 4, and D water operators get a minimum number of training credit hours (TCHs) in particular categories of training classes. This does not apply to Class 1A or 1B water operators or wastewater operators.

Training Classes
Classes offered by Vermont Rural Water will be categorized starting in January 2026. Look for a class’s category in the description on our website and on your training certificate.
For classes offered prior to 2026, use this list to look up the category.
If a training class is relevant to multiple categories, the operator may choose which category to apply it towards. A class providing 3 TCHs or less can only be applied to one category. A class providing 4 TCHs or more may be applied to multiple categories in half-hour increments.
Renewal
Class 2 and 4 water operators are encouraged to categorize their credit hours for the 2026 renewal cycle and will be required to do so for the 2029 renewal cycle.
Class 3 and D water operators will be required to categorize their credit hours for the 2028 renewal cycle.
Operators should use ANR’s new nFORM to renew their certifications. Starting in 2026, the nFORM will include “buckets,” allowing operators to list their training classes by category.
Operators must provide documentation of credit hours earned, such as training certificates.
