An Act relative to dental hygienist reciprocal licensure

Maddy summaryThis bill establishes a pathway for dental hygienists to obtain licensure in the state through reciprocal agreements with other countries or provinces. It allows individuals who are at least 19 years old and of good moral character to practice if they meet specific educational or experience requirements, such as graduating from an accredited program, completing a certain number of semesters as a student, or holding a valid license from a foreign jurisdiction with equivalent competency standards. The law also sets an annual fee for the examination process and requires applicants to pass a board exam covering essential dental hygiene subjects. Ultimately, the legislation expands the pool of eligible candidates by recognizing credentials from outside the state while maintaining established safety and qualification benchmarks.

An Act amending the charter of the town of Marshfield to make references to the board of selectmen gender neutral

Maddy summaryThis bill amends the town charter of Marshfield to replace the gendered term "board of selectmen" with the gender-neutral phrase "select board" throughout the document. The legislation directly affects the town's official records and legal framework by updating specific sections that reference the local governing body. By systematically striking out the old terminology and inserting the new one, the bill ensures that all future references to the town's leadership are inclusive and neutral in language. Once enacted, these changes update the town's foundational laws without altering the actual powers or duties of the officials who serve on the board.
