The Administrative Rules of Montana (ARM) Title 10, Chapter 55 Standards of Accreditation provides the framework for the evaluation process used in Montana schools. The standards outline the minimum guidelines and requirements of the evaluation system used by a school district. Implementation of the requirements of ARM 10.55.701 (4)(a) began in all Montana school districts in the 2013-14 school year. As directed by the standard, model evaluation instruments have been developed and published to assist school districts in meeting the state standards for educator evaluation. Model instruments promote the inclusion of professional growth components in the overall system.
