FREMONT — Save Fremont Students has collected more than $105,000 from community members, but with a goal of raising $4.5 million by July 15, volunteers are hoping to remind families before the school year ends today about the urgency of the campaign.

The grass-roots group, formed by Fremont parents and working in conjunction with the Fremont Education Foundation, is asking families to donate $475 each to save elementary prep teachers and keep class sizes lower for the upcoming school year.

More than 70 percent of donations made have been for amounts greater than $475, according to the Save Fremont Schools' website.

In recent days, students have pitched in on the group's efforts, holding rallies on its behalf. Group members also said that the number of volunteers has grown from five to more than 110 during the first two weeks.

Donors may designate whether they would like their money to go toward elementary or secondary schools.

Of the money that would go to elementary campuses, the first $1.8 million would pay for music, science and physical education teachers, and the second $1.5 million would go toward smaller class sizes in kindergarten through third grade. The school board has discussed raising K-3 class sizes to 30 students. Money from this campaign would cap classes at 27 students.

In addition to raising money for elementary schools, Save Fremont Students has a separate goal to raise $1.2 million to pay for secondary education teachers.

If the group does not fully meet its goals, the money collected will be divided among the campuses, proportional to each school's student population, organizers said. Money designated for elementary schools would go to the elementary campuses, and donations specified for secondary campuses would go only to middle and high schools.
