Lily-Mae Pilcher is one of only two pupils headteacher Clare Longden has known to never have a day off in her 16 years in charge of Bilston's Wallbrook Primary School.
The 11-year-old was also one of the first through the school gates when Year 6 pupils were allowed back into school last month.
Lily-Mae said: "I like school, my favourite subjects are maths and PE."
Mrs Longden said Lily-Mae is "amazing".
She said: "She is brilliant, when lockdown started her mum said she was gutted and asked what we're going to do about her 100 per cent attendance.
"As soon as we were allowed pupils back in June she was one of the first in.
"As well as enjoying maths and PE she's an absolutely amazing swimmer – I always joke she'll be in the Olympics."
Mrs Longden added: "One day Lily-Mae did something to her hand and had to get it checked out but she was back in school by the afternoon.
"She hasn't been shouting from the rooftops about her attendance but we have, it's quite an achievement."
Lily-Mae’s mum Charlotte Aston, 33, who she lives with in Coseley, said she was “really proud”.
