Charlie said he was ready to go and he had already got his uniform.
"I want to see my friends and I'm looking forward to learning to read books on my own," he said. "I'm most excited about seeing my friends."
He has had three school visits and said he liked his teacher, who he thought was nice. He had also liked playing on the playground.
"He's talking about school all the time," Miss Sadler said. "He doesn't like going to daycare anymore because he's excited about going to school."
Miss Sadler said she was happy Charlie was going to school as she felt like he was ready to go.
"But I'll be doing a sneaky drive-by at lunch time to see how he's going."
School rolls growing
Seventeen million dollars worth of expansions to Bay schools have been approved in the Bay already this year as school rolls continue to grow rapidly.
Western Bay of Plenty school principals quoted in the Bay of Plenty Times Weekend on Saturday said they were continuing to feel the squeeze from the region's growth as pupil roll numbers climbed, stretching resources.
In the Bay of Plenty, Papamoa College and Golden Sands School have undergone significant expansions, Otumoetai School, Bellevue School, Bethlehem School, Te Wharekura o Mauao and Brookfield School have new classrooms, and schools such as Pillans Point School are also on track for additional classrooms.
