Parents with children at Riverdale Elementary School believe enough kindergarten students have registered for the program to continue this fall.
Edmonton Public Schools is considering ending the program because of declining enrollment.
But parents said as many as 16 students enrolled in the program following an open house on Monday, which is raising hopes the school board will change its mind.
"We're expecting to hear them say that they'll restore the kindergarten program at Riverdale and we're happy to keep working with them to ensure that it and the school as a whole remain viable," said Mike Evans, president of the school's parent advisory council.
Edgar Schmidt, superintendent of Edmonton Public Schools, will announce his decision Tuesday.
"What we need to do is verify those registrations and look at overall enrollment numbers to know whether or not it's viable to have a kindergarten class," said Cheryl Oxford, who speaks for Edmonton Public Schools.
Earlier this year, the board suggested that having 15 registered students would be enough to keep the kindergarten open.
Kevin Minaker's son attended kindergarten at the school and he wants his daughter to get the same opportunity.
"I want my kids to have a sense of community," he said. "They play soccer down here. They play hockey on the outdoor rink. That's where you make friends that you'll possibly have for the rest of your life."
