Local levels: Level 1 Water Treatment; Level 2 Water Treatment; Level 3 Water Treatment; Level 4 Water Treatment. Separate Well System exam category also exists.
WPI/ABC exam provision is confirmed, but standardized versus customized status is not. DEQ links ABC Need to Know Criteria for each local level; neither those links nor its generic standardized sample-question disclaimer establishes Wyoming's standardized exam use or a local-level-to-WPI-class crosswalk.
No state-matched course is linked for this stream yet.
'Water treatment facilities come in Levels 1 through 4.' Separate sections name Level 1–4 Water Treatment and link ABC Need to Know Criteria. The sample-question disclaimer says samples are 'not necessarily representative of current exam content.'
Page 1: Wyoming water and wastewater operator certification exams 'are provided by Water Professionals International (WPI) and ABC Testing and proctored by PSI Services, Inc.' It does not identify standardized versus customized exams.

Local levels: Level 1 Wastewater Treatment; Level 2 Wastewater Treatment; Level 3 Wastewater Treatment; Level 4 Wastewater Treatment. Separate Lagoon System exam category also exists.
Wastewater evidence was checked independently. The state handbook confirms WPI/ABC provision, not standardization. The treatment page exposed grade headings but not accordion details; neither standardized exam scope nor WPI class correspondence was verified. Lagoon System must remain a distinct local route.
No state-matched course is linked for this stream yet.
'Wastewater treatment facilities come in Levels 1 through 4. Begin with the Level 1 Wastewater Treatment Plant exam and take all exams to reach the level of the facility where you work.' Headings name Level 1–4 Wastewater Treatment.
Page 1 expressly covers Wyoming water AND wastewater certification exams and identifies WPI and ABC Testing as their providers; standardized versus customized status is unspecified.

Local levels: Level 1 Distribution Systems; Level 2 Distribution Systems. Well System is a separate exam route for well-plus-distribution facilities.
The local ladder has two levels, not four. WPI/ABC provision is confirmed by the state handbook, but the opened distribution page did not expose its accordion details. No explicit standardized-use declaration or local-level-to-WPI-class correspondence was verified; matching level numbers are insufficient.
No state-matched course is linked for this stream yet.
'Distribution Systems come in Levels 1 and 2. Begin with the Level 1 Distribution System exam.' Section headings are 'Level 1 Distribution Systems' and 'Level 2 Distribution Systems.'
Page 1 identifies WPI and ABC Testing as providers of Wyoming water and wastewater certification exams, with PSI as proctor; it does not specify standardized or customized scope.

Local levels: Level 1 Collection Systems; Level 2 Collection Systems. Lagoon System is a separate exam route for lagoon-plus-collection facilities.
DEQ supplies collection-specific ABC criteria links for both local levels. Its reference to 'ABC’s Standardized Exams' describes generic sample questions, not an explicit declaration that Wyoming administers standardized collection exams. WPI/ABC provision is confirmed, but standardized/customized status and the two-level class crosswalk remain unverified.
No state-matched course is linked for this stream yet.
'Collection Systems come in Levels 1 and 2.' Sections link 'ABC Need to Know Criteria' for Level 1 and Level 2 Collection Systems. The standardized sample-question disclaimer says the samples are not necessarily representative of current exam content.
Page 1 confirms WPI and ABC Testing provide Wyoming water and wastewater certification exams; PSI proctoring is stated separately and does not establish standardization.
