Here are rubrics for assessing presentation & collaboration skills that BIE created for the PBL Starter Kit and makes available for downloading from this website. We’re interested in hearing feedback from teachers who try using the rubrics with students in a project. They are designed in a new style, without any middle columns, so teachers can mark a scale somewhere between “not proficient” and “proficient.”
