A teacher who has been employed by the District continuously for three consecutive school years, and who is then rehired for the next succeeding school year, shall achieve tenure in the District at the beginning of the fourth year.

A teacher who has acquired tenure in the District, but loses tenure because of a break in service, may reacquire tenure if the break in service was not the result of dismissal or non-retention, and did not last longer than one year. A teacher returning from a break in service not lasting longer than one year will reacquire tenure at the beginning of the second consecutive year of reemployment, provided the teacher performs a day of teaching services in the second year.

A teacher who has acquired tenure in another district will acquire tenure in this District, if the teacher's break in service was not the result of dismissal or non-retention, and did not last longer than one year. A previously tenured teacher who has been employed by the District continuously for two consecutive school years who is then offered a contract for the next succeeding school year shall achieve tenure at the beginning of the third year, provided the teacher performs a day of teaching services in the third year.
