Dive Brief:

• Los Angeles school officials now say fewer iPads will be needed to perform standardized student tests in the spring. 
• The change is expected to save $25 million, but raises questions about how the district arrived at its initial figure.
• The upcoming round of tests is a trial and the results won't count, but schools that participate must do so by computer.

Dive Insight:

In the scheme of a $1 billion rollout, the numbers may not be large. But the differences are still significant. Administrators initially said they would need about 68,000 iPads for testing, in addition to the tablets already deployed. Now, the district says only half that many would be needed for the upcoming year — and even that lower figure is being challenged.
