Contribute to the WC13 program

Your contributions are instrumental in designing an impactful and engaging Congress program.

Based on guidelines from the Alternatives Congress Trust to create a well-balanced program reflecting the 3Rs, WC13 Organizing Committee strives to integrate interdisciplinary content for diverse perspectives and learning experience.

Session Submission guidelines

It is now possible to submit a session proposal for WC13. All sessions within the WC13 program will be 60 minutes long. After submitting the session proposal, the Scientific Committee will review the session based on quality, innovation, and inclusivity. Potentially overlapping sessions may be merged. The session organizer will be informed of this in advance.

*Please read these guidelines before submitting a session.


  • Session Proposals are accepted under four main congress tracks and two formats as described below – select the most relevant track for your content and the best format for its delivery.
  • The WC13 International Scientific Advisory Committee strongly encourages proposals with 3Rs content spanning multiple disciplines and sectors.
  • Please strive to diversify your proposal by including interdisciplinary content, for example, refinement; reduction; replacement; toxicology; regulatory testing; biomedical research; disease models; technologies (in vitro; ex-vivo; in vivo; in chemico; in silico/big data/AI); regulatory acceptance; global harmonization; education; and bioethics/welfare.
  • Please integrate multisectoral content and speaker suggestions (from academia, industry, government, and not-for-profit) for diverse perspectives and a learning experience.
  • Please note that space is limited for proposed sessions. Sessions will be selected via peer review by the International Scientific Advisory Committee. The Organizing Committee reserves the right to combine sessions under a common track and propose additional speakers, as deemed suitable based on submissions and priority topics.
  • Session proposals are due by September 30, 2024, and can be edited until 1 PM BRT (GMT-3).

Session formats

Each session organizer may allocate 40-45 minutes of the 60-minute session to speakers. This means you can choose from the following:

  • Presentations of 1x 30 minutes + 1x 15 minutes including questions
  • Presentations of 2x 20 minutes including questions
  • Presentations of 3x 15 minutes including questions

The remaining 15-20 minutes within the session will be filled later with abstracts that are submitted.

There are two formats: a Symposium or a Workshop. A symposium is a formal platform session featuring in-depth analysis of a 3Rs topic of wide interest that explores new data, new technologies, and new concepts in the field. It's an information-rich session tailored for a diverse, multisectoral audience. A symposium is a 60 minute session with a conventional platform format suitable for 4 speakers. Speaker suggestions should be provided on the proposal submission form and/or allocated from accepted abstracts.

Workshop is a more interactive session (can include hands-on exposure to technology) where 4 speakers will discuss specific topics related to novel discoveries, challenges and emerging needs in a field of 3Rs interest (with the hope of generating discussion to obtain tangible outcomes to address those needs and challenges). A workshop is a 60 minute session – must allocate ample time for discussion with attendees.


Craft Session Title and Select Theme and Format

The title should be concise yet informative. Use the 3Cs—be creative, concise, and catchy. Carefully select the Track for your proposed session (select from four options) and the most appropriate format for delivery (select from 2 options). The International Scientific Advisory Committee reserves the right to propose changes to the format of tentatively accepted sessions in order to accommodate the best fit for your session within the overall scientific program of the congress.

Draft the Session Description/Abstract

This section should provide concise yet comprehensive details for peer review by an interdisciplinary, multisectoral International Scientific Advisory Committee. The session's purpose should be clearly defined, describing the subject matter, emphasizing the research, innovation, concepts, and challenges/issues to be addressed within the selected theme and format. The Session Description/Abstract is limited to 5,000 characters (including spaces), and should avoid the use of uncommon abbreviations and technical jargon. The Scientific Advisory Committee should be able to discern the content and role of proposed presenters solely from the proposal description. Speaker names and titles must not be included in the abstract, as this information will be available to the Scientific Advisory Committee through the speaker identification segment of the proposal portal.

Designate Chair/Co-Chair and Suggest Speakers

You may suggest 1-4 speakers per session and designate roles as Chair, Co-chair, or Speaker. An individual cannot be a Chair for more than one proposal, but may serve as a Co-Chair for a second proposal. The Scientific Advisory Committee strongly encourages session proposals to accommodate the integration of additional speakers—to be selected from submitted, accepted abstracts. Please also indicate whether this will be a sponsored session.

Declare Conflict of Interest

Please declare any conflict of interest (personal, financial, or otherwise) that could potentially interfere or undermine the rigour and objectivity of the proposal. If there is a conflict of interest, clearly state the source and nature of the conflict.


Follow the steps outlined on the Proposal Submission page to enter all pertinent information. The Session Organizer serves as the primary contact for all communication with the WC13 Congress Secretariat. It is the responsibility of the Session Organizer to submit the proposal using the Proposal Submission portal by the designated deadline (September 30, 2024). It is also the Session Organizer’s responsibility to ensure that the Chair, Co-Chair and the Speakers receive all pertinent session information if granted tentative acceptance of the session for the scientific program.
