This study investigated the level of concern in teachers and administrators regarding the adoption of a new math curriculum in the adoption's second year of implementation. Utilizing the Stages of Concern Questionnaire, based upon the Concerns-Based Adoption's Model as the instrumentation for the study, the findings of the study revealed that there was no significant difference in the levels of concern between the teachers and administrators. Additionally it was found that the majority of the teachers' and administrators' level of concern was at the "unconcerned" stage.
