LOS ANGELES (AP) — The nation's second-largest school district will spend $135 million during the spring semester as part of its ongoing $1 billion plan to provide iPads to all students. 

The Los Angeles Times reports the spring expenditure would pay for more than50,000 iPads for students, teachers and administrators.

The plan also calls for buying more than 67,000 tablets to allow for all students to take new state standardized tests with the iPad on a rotating basis.

At the end of the spring semester, purchases are expected to stop for as long as a year while the program is analyzed.

The rollout of the iPads earlier this year quickly encountered problems when more than 300 students at three of the first campuses quickly cracked their security settings and began surfing the Internet.
