Training Coordinator Resources

In order to maintain and promote the American Orchid Society Judging System, a concerted effort toward the recruitment and training of new judges is imperative. Orchid judging is largely taught by way of observation – recruits observe and assist credentialed judges thereby learning and assimilating necessary skills. While it is impossible to be intimately familiar with each orchid genus, we have experienced individuals at each center who are highly knowledgeable and skilled in particular groups of genera. In addition to information about judging the orchids themselves, The Handbook includes vast sections on functional aspects of judging center and show judging operations, conduct, including ethics and bias management, appropriate research and other skills necessary to becoming a successful orchid judge. The AOS Training Coordinators' Resource Page is intended as a resource to training coordinators and centers throughout the system. Here you will find a variety of training tools, student and probationary assignments, and materials for centers' educational sessions.

This is a living document. As mentioned above, each center has subject experts. We strongly encourage experienced judges to submit training assignments, tools and educational materials to for inclusion on this page.


Guidelines for Educational Presentations:

While not everyone has access to PowerPoint, it has become the standard for presentation software. If you develop an educational program or training tool in PowerPoint, it is important to recognize that other presenters may not have your level of knowledge on the subject at hand. Therefore, it is important to include detailed speakers' notes. Within PowerPoint, this is easily accomplished by typing your detailed notes directly into the 'Notes' section. These are not displayed on the screen, but appear on the screen of the controlling computer.

If you do not have access to PowerPoint, you can use a variety of presentation or desktop publishing software packages to develop your materials. Be sure to begin by setting the page for [landscape]. When complete, use [File][Save as…] or [File][Export] to save your file as a PDF (Adobe Acrobat's Portable Document File). The PDF export is available in most, but not all, software packages. If [PDF] is not an option within your software, search the internet for ‘convert to PDF’ for an online conversion from your file type).

Please remember that it will be necessary to include a separate file with detailed speakers' notes. To present your PDF 'slides,' use the free Adobe Acrobat Reader, select the [View] menu and choose [Full Screen]. Your 'slides' will appear in a fashion very similar to a PowerPoint presentation & you will be able to advance slides with a simple mouse click or down arrow. It won't have the bells & whistles available in PowerPoint, but can be just as effective so long as the speaker is provided with sufficient detail to fill in the gaps and informational tidbits between the bullet points and visual aids in your presentation.
