COLUMBIA, S.C. (AP/WVOC) - State Superintendent of Education Mick Zais is again requesting millions of dollars for new school buses and asking lawmakers to close a teacher bonus program to new entrants.

Zais told a House budget-writing panel Wednesday that more than 60% of South Carolina's state-owned buses exceed 15 years old.

He says it would take $34-million to comply with a 15-year replacement cycle legislators passed in 2007.

His agency's last major purchase of 342 buses was in December 2012.

Zais also asked for $34-million last year, and lawmakers approved about $23-million, which could buy 280 buses.

The education superintendent also repeated his recommendation to close an incentive program for teachers who earn national certification, which provides an annual bonus of either $5,000 or $7,000 for 10 years.
