Section 411-404-3 - Teachers Creditable Service After June 30, 19911. Creditable service will be granted to teachers paid on a contractual or daily basis as follows: A. For purposes of this sub-section, a "full-time teacher" is a teacher who worked, in the pay periods covered by a payroll report, 100% of the regularly scheduled standard days prescribed by the employer for employees in the same class and school administrative unit. For the purpose of this paragraph, "full-time" must be at least 180 days.B. Full service credit for the periods covered shall be granted to a teacher who works, in the pay periods covered by a payroll report, 100% of the days worked by a full-time teacher.C. A teacher who works less than 100% of the days worked by a full-time teacher, in the payroll periods covered by a payroll report, shall be granted creditable service equal to the ratio of days worked by the teacher to 100% of the days worked by a full-time teacher.D. Notwithstanding sub-sections B and C, a teacher shall continue to accrue creditable service while on a leave of absence without pay of up to 15 work days duration each year. If a teacher's regularly scheduled work year exceeds 180 days, the number of days in the previous sentence shall be increased to the number of days that would equal one month (i.e., .083 of one year) of creditable service.2. A teacher on a sabbatical will be granted one year of creditable service if paid at least one-half of the teacher's contract salary for the previous year. If less than one-half of the teacher's contract salary is paid, creditable service equal to the ratio of the teacher's salary paid to 50% of the teacher's contract salary shall be granted.3. Service credit for a teacher compensated by an hourly rate of pay is granted based upon the number of hours worked pro-rated against 900, and the resulting portion of a year of service is earned.94- 411 C.M.R. ch. 404, § 3
