Ed. Code, § 45041

A person in a position requiring certification qualifications who serves less than a full school year shall receive as salary only an amount that bears the same ratio to the established annual salary for the position as the number of working days he serves bears to the total number of working days plus institutes in the annual school term, and any other day when the employee is required by the governing board to be present at the schools of the district. Notwithstanding any provisions of this section to the contrary, a person in a position requiring certification qualifications who serves a complete semester shall receive not less than one-half of the established annual salary for the position. This section shall not be so construed as to prevent the payment of compensation to a person while on leave of absence when the payment of the compensation is authorized by law.

In the event any such person dies during the school year, his estate shall be entitled to receive, as salary owed to the decedent, an amount that bears the same ratio to the established annual salary for the position as the number of working days he served bears to the total number of working days plus institutes in the annual school term, and any other day when the employee was required by the governing board to be present at the schools of the district, less any salary paid to the decedent prior to his death.
