Workshop Guidelines

The Workshop Guidelines – From Registration to Travel Reimbursement document contains everything a workshop participant needs to know to attend the PPCDL Workshops. This document contains sections on what you need to know before registering, how to register, workshop policies, how to make travel plans, what is an allowable expense and how to get reimbursed. Additionally a short video is (or will be made) available to review the document and help guide those looking for specific information.

Registration deadline: December 20, 2023.

The Bioinformatics Module on High Through-Put Sequencing (HTS) will have two parts this year, combining a 1-day, virtual session with the 3-day, in-person session. This workshop is capped at 6 participants to promote more interaction between the instructors and participants. Please note, participants MUST commit to attending both parts of this workshop to register. Three workshops have two date options to allow more to attend. Each session will provide the same information so please choose the one that works best for you. The workshops are listed with “Option 1” or “Option 2” in the description. Please include your choice of dates in your registration request for the in-person ELISA Proficiency Preparation Workshop, the virtual Sample Submission for Confirmatory Testing Workshop and the virtual Production & Validation of Diagnostic Assay Controls Workshop will be offered in two sessions.

Travel and reimbursement information

All participants should have received a letter pertaining to accommodations and transportation information for their workshops.


Travel reimbursements will be processed using the same method introduced in 2023. Travel reimbursements must go to the institution and NOT to the participant. As always, there is no registration fee for attending any workshop(s) or for the meeting materials provided. The workshops are supported by a PPA 7721 Cooperative Agreement. Travelers will submit a letter, on their institution letterhead, simply listing their reimbursable travel expenses. A template is available below. The reimbursement check will be made out and mailed to the institution. And to demonstrate the collaboration between the NPDN and USDA-APHIS-PPQ-S&T-PPCDL, each traveler will be provided a scholarship up to $1,500 for one workshop or $2,000 for two or more workshops. Any additional costs must be covered by internal funds.
