The SubStrength Finder is a set of 78 questions for potential substitute teachers to identify strengths and weaknesses prior to entering the classroom, with the assumption that the potential substitute has had little or no experience in the classroom. It provides feedback to both the substitute and the district on where improvement is needed and direction on how to do so. Substitute teachers are directed where to look in the SubSkills section of the site to further develop the skills necessary to be effective in the classroom. This is the first component of a comprehensive and customized professional development plan for substitute teachers.
