34 CFR § 686.40 - Documenting the service obligation.
(a) If a grant recipient is performing full-time teaching service in accordance with the agreement to serve or repay, or agreements to serve or repay if more than one agreement exists, the grant recipient must, upon completion of each of the four required elementary or secondary academic years of teaching service, provide to the Secretary documentation of that teaching service on a form approved by the Secretary and certified by the chief administrative officer of the school or educational service agency in which the grant recipient is teaching. The documentation must show that the grant recipient—
(1) Taught full-time in a low-income school as a highly qualified teacher as defined in § 686.2(d); and
(2)
(i) Taught a majority of classes during the period being certified in any of the high-need fields of mathematics, science, a foreign language, bilingual education, English language acquisition, special education, or as a reading specialist; or
(ii) Taught a majority of classes during the period being certified in another high-need field designated by that State and listed in the Nationwide List, in accordance with § 686.12(d).
(b) For purposes of completing the service obligation, the elementary or secondary academic year may be counted as one of the grant recipient's four complete elementary or secondary academic years if the grant recipient completes at least one-half of the elementary or secondary academic year and the grant recipient's school employer considers the grant recipient to have fulfilled his or her contract requirements for the elementary or secondary academic year for the purposes of salary increases, tenure, and retirement if the grant recipient is unable to complete an elementary or secondary academic year due to—
(1) A condition that is a qualifying reason for leave under the Family and Medical Leave Act of 1993 (FMLA) (29 U.S.C. 2612(a)(1) and (3));
(2) A call or order to Federal or State active duty, or Active Service as a member of a Reserve Component of the Armed Forces named in 10 U.S.C. 10101, or service as a member of the National Guard on full-time National Guard duty, as defined in 10 U.S.C. 101(d)(5); or
(3) Residing in or being employed in a federally declared major disaster area as defined in the Robert T. Stafford Disaster Relief and Emergency Assistance Act (42 U.S.C. 5122(2)).
(c)
(1) A grant recipient who taught in more than one qualifying school or qualifying educational service agency during an elementary or secondary academic year and demonstrates that the combined teaching service was the equivalent of full-time, as supported by the certification of one or more of the chief administrative officers of the schools or educational service agencies involved, is considered to have completed one elementary or secondary academic year of qualifying teaching.
(2) If the school or educational service agency at which the grant recipient is employed meets the requirements of a low-income school in the first year of the grant recipient's four elementary or secondary academic years of teaching and the school or educational service agency fails to meet those requirements in subsequent years, those subsequent years of teaching qualify for purposes of satisfying the service obligation described in § 686.12(b).
