DEADLINE EXTENDED! Now Accepting Updated National Core Manual Pre-Sales and Requests for Modifiable File from PERC - by 10/3/25!

The Pesticide Educational Resources Collaborative (PERC) is ready to release the 3rd edition of the National Pesticide Applicator Certification Core Manual and Exam! The manual and exam bank are intended for the certification of commercial and private pesticide applicators in the core competencies related to laws and safety. The revision includes the newly required competencies under the 2017 revised Certification of Pesticide Applicators Rule (40 CFR Part 171). More information about the manual and exam is provided here, and a full description of adoption options is provided here. 

Select one of the Options below that best suits your institution’s needs.

Option 1: Adopt Manual “As Is", Purchase Reduced Cost Copies, Re-sell Locally

• Who may order? Certifying authorities (as defined by the U.S. EPA) may direct customers to buy copies directly from the PERC Store, or they may choose to pre-order reduced cost printed copies of the full manual, which they or their “designees” may re-sell locally at retail. Designees might include their Pesticide Safety Education Program (PSEP) or a distribution vendor. Certifying authorities should estimate the number of printed manuals needed for the next 12 months. PERC will not print the full manual again until 2026, and PERC/UCD will be the sole distributor for resale copies of the 3rd edition. The cost for future print runs could be higher, pending order volume and vendor expenses. We encourage folks to participate in this print order this fall.
• How long is the pre-sale window? And what happens if I miss it? The window for pre-sales has been extended from 4 weeks to 6 weeks and is now 8/25/25 – 10/3/25 at a reduced cost. Eligible purchasers will submit payment directly to the reproduction vendor, Gleason’s Printing. After the pre-sale ends, printed copies may be purchased at the retail price (TBD, anticipated to be $50-$65) from the PERC Store once available.
• How can I place my order? To order your copies at the reduced cost during the pre-sale window, use this form. Be prepared to indicate your method of payment, contact information for billing, tax-exempt status, contact information for shipping, etc. Gleason Printing accepts payments made via credit card, purchase order, and Automated Clearing House. Once we have your information, then we will forward it to Gleasons, who will work with your contacts directly for invoicing, payment, and shipping arrangements. PERC will not post this offer for reduced cost copies in the PERC Store. This is a special offer only for certifying authorities and their PSEPs.
• What is my cost? Reduced-cost copies are available to certifying authorities and their designated PSEPs: $25 each for orders under 1,000, $20 each for orders of 1,000–1,999. For orders of 2,000 or more, contact PERCsupport@ucdavis.edu for pricing. Purchasers shall assume the cost of shipping, handling, and credit card fees and these will be made available by Gleasons (the printer/distributor) once PERC provides them with the information supplied in the form. Certifying authorities should estimate the number of printed manuals needed for the next 12 months. PERC will not print the full manual again until 2026, and PERC/UCD will be the sole distributor for resale copies of the 3rd edition. However, retail-priced copies will be available in the PERC store when they are available.
• When will I receive my copies? Purchased manuals should arrive no later than December 2025 pending no supply chain issues. We will keep you apprised of any delays.
• Are there restrictions on resale pricing? No, this is up to the certifying authority / PSEP. However, it is our hope that resellers will collaborate on the retail price out of fairness. We suggest offering it for $50-$75, which reflects the rigor and defensibility of the technical writing and professional graphic design/layout.

Option 1A: Adopt Manual “As Is", But Not Ready To Purchase Copies to Resell, or Do Not Intend to Resell

• What if my organization wants to adopt the manual “as is” but we are not ready to purchase copies? PERC won’t leave you behind! You may participate in the next print run planned for 2026 and purchase copies then. In the meantime, you may direct your users to obtain copies through the PERC Store once available. Kindly use this form to let us know by 10/3/25 this is your intent, and estimate the number of manuals your users will need in the next 12 months. This will help inform us so that an adequate supply can be made available.
• What if my organization wants to adopt the manual “as is” but we don’t want to resell and just want to direct users to the PERC Store?  Kindly use this form to let us know by 10/3/25 this is your intent, and estimate the number of manuals your users will need in the next 12 months.  This will help inform us so that an adequate supply can be made available.

Option 2: Adopt Manual to Modify, Request Modifiable Digital File, Distribute as Desired

• Who may request? Certifying authorities or their PSEPs may request a modifiable digital file of a simplified manual to adapt and modify, adhering to a license agreement with necessary elements described here. Since file-sharing is not permitted, each entity must request their own copy via a separate license agreement.  However, it is generally assumed that only one entity (most often the PSEP) is the one doing the actual modification, and it’s a rare exception that both PSEP and SLA would both need a modifiable copy.
• How will the simplified manual file differ from the full manual file? The simplified manual file will arrive without a cover, have a different interior spot color and font, and lack certain design elements of the full manual. The technical content will be the same as the full manual. Modifiers should be proficient in working with Adobe InDesign files for the best results, as PERC cannot assist with editing the manual. The InDesign file may be accessed on either a Mac or PC. Fonts and illustrations will be embedded/linked.
• How long is the request window open? And what happens if I miss it? The window for requests for modifiable files has been extended from four (4) weeks to six (6) weeks during the pre-sale window. If you miss the window, then you will not be able to request a modifiable file again until 2026. The pre-sale and request for a modifiable digital file window has been extended and is now 8/25/25 – 10/3/25.
• How can I request the modifiable file? To request the modifiable digital file, use this form.
• What is my cost? Because of a significant budget cut to PERC in Year 5 with no funds awarded, UC Regents reserves the option to assign a modest licensing fee to cover the effort needed to prepare your license agreement and review and sign off on your modified work. Depending on the extent of your changes and review required, the licensing fee will be $250-750. If you request a file and do not complete the Modification, then there will be no fee. However, it’s PERC’s expectation that if you request the modifiable file that you have every intention to create the modified manual. 
• When will I receive my file? We will forward requests to the campus copyright office each week so requesters may begin the licensing process. PERC will serve as the initial liaison with campus, and then the requester may work with them directly on their license. PERC will provide the requested file to the Licensee using a secure method within 10 business days once we are notified of a countersigned license agreement. Take note of the 3/31/26 deadline for PERC to verify the compliance of your modified manual with the license terms before you can distribute it. Entities should plan to submit their drafts to PERC no later than 3/2/26 to allow ample review and response time. We encourage you to submit your Modification at any time before that. It is PERC’s goal to review all Modifications upon receipt and return with comments/approval in 10 business days, to the extent possible.

Option 3: Do Not Adopt Manual

• Certifying authorities who select this option may still request a copy of the exam bank from EPA once available. PERC requests you let us know of your decision for option 3 by emailing us at PERCsupport@ucdavis.edu so we know not to reach out to you.

Licensing Requirements

Please note that the use of PERC certification and training manuals in modified form is subject to a license agreement with the UC Regents. Entities requesting a modifiable digital file must:

• Sign a license agreement with the UC Regents.
• Make required changes, including cover/title updates and inclusion of a section on state laws and regulations.
• Remit a licensing fee (generally $250–$500) for UC review of the modified manual to ensure compliance with license terms.
• Ensure that only the modified version may be distributed or posted online. The PERC master source file may not be shared or posted by any party (EPA, PERC, certifying authorities, or PSEPs).

Failure to comply with the license agreement may result in penalties, including fines of up to $300,000 for license violations.

Bilingual Glossary of Terms Applicable to Pesticide Certification and Training

PERC recognized the need for national certification and training resources to be widely accessible to broaden the reach of pesticide safety and certification to Spanish-speaking populations, as well as to standardize Spanish translations across PERC’s works. The Core Manual Spanish translation team was able to create a Bilingual Glossary of 149 Terms Applicable to Pesticide Certification and Training. PERC intends to use this glossary for all future translations of PERC’s works. The glossary provides a “meaning for meaning” translation and offers synonyms to identify alternative translations that may be used. PERC will use this bilingual glossary to translate further works, as well as provide a recommendation for translating pesticide safety and certification-related works.
