Izaak Miller, from Cheshunt, Herts, can write the English, Greek and Arabic alphabet and is now planning to get started on Russian, thanks to his love of languages.
A four-year-old boy has become a member of Mensa and already knows all 50 American states and the alphabet – in three different languages.
He passed the Mensa admission test aged three and has now earned his place in the prestigious intelligence club.
The talented toddler taught himself to read books by two and can write the English, Greek and Arabic alphabet – despite having no Greek or Arabic heritage.
Mum Michelle Nelson, 32, said “he just loves language” and has already asked for books of the Russian alphabet.
With a reading age of seven years ten months and maths skills usually seen in the average six-and-a-half-year-old, his Mensa acceptance letter arrived last month.
Ms Nelson, a secondary school teacher, said: “Izaak is my only child so going through the process of parenting I was shocked that one day he could just read.
“It was more from being outside with him and him reading signs on the bus and the underground, reading names of stations and reading instructions on posters like ‘please sit down take a seat.
“People were looking at him and asking whether he was at school because they couldn’t believe a child that young could read.
“Every time I walk out the house someone compliments him.”
Izaak can also count to ten in Spanish, knows all the planets in order, and spends time putting alphabet blocks by corresponding items, such as ‘A’ next to his ‘aquarium.’
Ms Nelson, from Cheshunt, Herts, added: “I had to tell the nursery [about his Arabic] – they thought he was writing nonsense!
“They couldn’t believe it because none of them know that alphabet.”
Izaak took the Wechsler Preschool and Primary Scale of Intelligence test with educational psychologist Dr Peter Congdon.
Dr Congdon recommended he gets tested again in two to four years to see how his IQ improves.
His report described Izaak as ‘a child of very superior general intelligence and scholastic attainments to match.’
Because Mensa’s tests can not be applied to under 10-year-olds, they must take an independent assessment beforehand as prior evidence for the application.
The youngest-ever member was two years and four months old at the time of joining.
