When you receive the Report Acceptance Email, it should tell you several things:
One of the most important parts of the email for you to examine is the list of applicators. The email shows the certification ID and the name that the DEC has recorded for that certification ID for every certified applicator included in your report. Confirm that all of the applicators that should be in your report are in the list and that no one who should not be in your report is in the list. See this FAQ for typical reasons why an applicator might be missing from the list.
