The district announced in January that it would spend about $4.2 million to hire 1,087 aides and assign two to patrol each of its 400-plus elementary schools. So far, 443 aides have been hired and assigned to 327 schools.
Officials could not immediately say Tuesday how many more will be hired or whether there's a timeline for bringing them aboard.
The district previously said the campus aides would be equipped with two-way radios and would work three hours daily, keeping an eye open for student conflicts, potential threats and other signs of trouble.
The plan was devised in response to the Dec. 14 shooting at Sandy Hook Elementary in Newtown, Conn., that killed 20 first-graders and six adults.
The district already had about 1,000 security aides assigned to its middle and high schools.
In addition, Los Angeles Unified's 350-member police force is assigned full time to every high school and also patrols K-8 schools on a daily basis.
After Sandy Hook, the Los Angeles Police Department beefed up patrols around local campuses and added walk-and-talk school visits to their duties. LAPD spokesman Richard French said Tuesday that program is still in force.
