TCU’s enrollment growth isn’t limited to its undergraduates.

Silver Frogs, an extended education program for people over 50, has grown from 160 members to 500 since it started in 2015.

Members pay $145 individually or $260 for couples for four weeks of programming. Non-credit classes and lectures are offered during the fall and spring. Classes are 90 minutes a week for four weeks, and lectures are one session for 90 minutes. There are 104 offerings this semester.

“We sell out every semester,” said Julie Lovett, Silver Frogs liaison. “We have a retention rate of 89 percent right now from semester to semester.”

She said there’s a range of options.

“We have interest groups for arts, ethics, women and wine, a men’s breakfast club, square dancing, German,” Lovett said.

Barbara and David McClellan are in their second semester of the program and are taking the rock ‘n’ roll class.

“We both grew up in the ’60s and love the music,” Barbara McClellan said.

Barbara is a TCU graduate, but that is not a requirement to be a member of Silver Frogs.

Lovett said the response has been unbelievable.

“We’ve really been able to maintain a sense of community with the Silver Frogs,” she said. “We’re always looking for new space to hold our programs, but at some point, you get too large where you become more of a number and we never want to get that big.”
