If Carwyn James' school attendance is anything to go by he should have nothing to fear when he collects his A-level results on Thursday.
He has not missed a day since he first went to primary school 13 years ago.
The 18-year-old left Ysgol y Preseli in Pembrokeshire in June and plans on taking a well deserved gap year before studying architecture at university.
It is a family trait as his mother Anne never missed a day's school, neither did his late grandmother Nellie.
Younger brother Aled also shows every sign of maintaining the tradition with an unbroken attendance to date.
Pembrokeshire council said the three generation 100% attendance is a record for the county.
Welsh-speaker Carwyn, who started his school life at Ysgol Gynradd Crymych, said he was fortunate with his health and only ever suffered "the odd sniffle."
"I enjoyed school because of the atmosphere, which in my opinion is unique to Preseli," he said.
"You just get up and go don't you?"
Carwyn, who enjoys farming, playing rugby and acting in his spare time, added: "I was honoured to be head boy in my final year, which made it very special for me.
"It's great to see your friends every day and once you reach the sixth form teachers become more friends than anything else. School is a happy place to be."
Carwyn was brought up on the family farm in Crymych. His father died when he was young and he helps care for his mother.
He aims to take a gap year working at a local architect's office and helping out on the family farm, before studying architecture at university.
Council cabinet member Huw George said: "His is a remarkable achievement in this day and age.
"Carwyn's school attendance record is to be applauded as is that of his brother, mother and grandmother. It's a family tradition of the highest order."
