WDI-O Credentialing Training

Step 1: Complete the VPMA Certified WDI Inspector Workshop 

• Candidates must apply directly to VPMA by filling out an application along with paying the course fee. VPMA sets its own schedule and location for this course so visit VPMAonline.com to learn about upcoming training opportunities.  MSPCA will note the dates and locations on our web site as we are notified by VPMA. We have negotiated with VPMA for our members to enroll at the discounted VPMA Member price. You will need to acquire a discount code from VPMA. You are NOT required to meet the stated VPMA “prerequisites”.
• Secure the study material from VPMA and study the material BEFORE attending the course.
• Attend the course and pass the examination proctored at the completion of the instruction. You will NOT receive a certificate from VPMA.

Step 2: Complete the MSPCA WDI-O Supplement

• Once you’ve completed the VPMA course and passed the test, VPMA will email the results to MSPCA. You will then be given a link to purchase the MSPCA Supplement for $50. Once you have purchased the MSPCA Supplement you will receive an email packet containing:
  • The Maryland Supplement Exam, which is open book
  • The WDI-O Inspector pledge
  • MDA Regulations The MD1 Form and a copy of the MSPCA suggested guidelines for MD-1 inspections
• After receiving the MSPCA Supplement, do the following:
  • Complete the open-book exam by using the MD. Dept. of Agriculture’s “Regulations Pertaining To The Pesticide Applicators Law”, the MD1 form and “MSPCA Suggested Guidelines”
  • Sign the pledge and upload to your MSPCA Profile (directions will be provided) 
• After passing the exam and signing the pledge, you will then be awarded a “WDI-O Credentialed Inspector” certificate and issued a unique credential number.
• Maintaining your credential will require adherence to the principles taught in the course as well as an obligation to attend a MSPCA conducted re-credential course at least once every 3 years.
