A Cost Analysis of Traditional Professional Development and Coaching Structures in Schools

Current achievement data indicate a public health concern, whereby the majority of students are not proficient in reading or math. Teacher professional development is frequently the preventive mechanism schools utilize to improve instruction, student achievement, and subsequent long-term economic and health-related outcomes. This study used the ingredients method to examine the costs associated with two common structures of professional development: traditional workshops and coaching. Results suggested that the cost per educator per contact hour ranged from $138.29 to $158.45 for workshops and was $169.43 for coaching, in 2017-2018 US dollars. The distribution of costs indicated that local districts incurred the majority of the costs for traditional workshops (i.e., range of 74.76% to 81.03%), whereas regional providers incurred the majority of the costs for coaching (i.e., 58.75%). Marginal costs, or the costs for one additional participant at one traditional workshop, ranged from $663.64 to $1132.78 and were $441.32 for coaching an additional peer teacher within one school building. Marginal costs increased to $2060.21 when coaching an additional peer teacher in an additional building. Implications for practice and suggestions for future research are discussed.
