              4             3            2             1    SCORE:
TOPIC KNOWLEDGE, ACCURACY, AND DETAILS. Posters, powerpoints, or presentations are fine, full of important scientific details and accurate information. Your poster, PowerPoint, or presentation is accurate and detailed enough to keep you working. Includes all but one of the items needed for posters, powerpoints, or presentations. Some required items were missing.  
LABELS AND GRAMMAR. All important elements of your poster, PowerPoint, or presentation are clearly marked with labels that can be read from at least 3 meters away. There are no grammatical/mechanical errors in your poster, PowerPoint, or presentation. Posters, PowerPoint presentations, or almost any important element of your presentation are clearly marked with labels that can be read from at least 3 meters away. Your poster, PowerPoint, or presentation has 1-2 grammatical/mechanical errors. Posters, PowerPoint presentations, or many important elements of a presentation are clearly labeled so they can be read from at least 3 meters away. Your poster, PowerPoint, or presentation has 3-4 grammatical/mechanical errors. Labels are too small to display or important items are not labeled.
