As used in this chapter, "reasonable effort" means the:

(1) Extension of the school year to and through June 14th; and

(2) Use of scheduled vacation days and foreseeable school closure days, to attain the minimum number of school days and district-wide annual average total instruction hour offerings required by law. In no case, except as provided in subsection (3) of this section, shall a school district or charter school be considered to have made a reasonable effort unless at least three school days, per incident, and district-wide annual average total instruction hour offerings which have been lost have in fact been made up.

(3) Where a school district or charter school resides in a county which was declared a state of emergency proclamation by the governor due to fire, flood, explosion, storm, earthquake, epidemic, or volcanic eruption, and the emergency impacted district-wide facilities or operations, the superintendent may consider school district or charter school applications to have met the "reasonable effort" test by providing at least the district-wide annual average total instruction hour offerings.
