Beau's teachers describe him as an avid speller whose Christmas request is a spelling app to continue building his vocabulary and spelling ability.
Proud mum Kate Mounter said Beau was still considering his future career path but being a marine biologist, designer or engineer all appealed to him.
It may be that spelling is in his blood — his great-grandfather, Robert Dunn, was a Whangārei-based journalist who started working at the Northern Advocate at the age of 15. He eventually became editor and retired in the 1960s.
ICAS (International Competitions and Assessments for Schools) competitions are carried out online in 20 countries and cover a range of subjects for pupils in Year 3 and up. They are designed to recognise and reward academic excellence.
