IZAAK MILLER is just 4 years old but he already knows all 50 American states and the alphabet in three languages.

He even taught himself two of the languages – Greek and Arabic – using Youtube videos as the family have no background in those.

Spotting his potential, his parents had his IQ tested and they were told its currently 154 — the top 1 percent for his age range.

He passed the admission test for prestigious intelligence club Mensa aged three and his acceptance letter arrived on April 24.

The youngest-ever member was two years and four months old at the time of joining but Miller’s achievement is still pretty amazing.

Mum Michelle Nelson, 32, said “he just loves language” and has already asked for books of the Russian alphabet.

Tests showed that his reading age is seven years ten months and maths skills are usually seen in the average 6-and-a-half-year-old.

Michelle, a secondary school teacher, said: “Miller is my only child so going through the process of parenting I was shocked that one day he could just read.” 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. Michelle has an 8-year-old step-daughter, Layla Miller, who she has raised since she was three, but as she missed the first few years of her life, she didn’t know what to expect with Izaak.

Miller 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.”

Michelle, from Cheshunt, Hertfordshire, 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.”

Miller 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 Miller 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.

People often assume that Michelle is homeschooling him earlier because she is a teacher but she said she hasn’t been. “He picks up everything like a sponge. He likes to ask questions and act like a teacher,” Michelle added.

“Every time I look at him I feel nothing but pride. People say to me he is going to go on to do fantastic things. I have high aspirations for him. I know he can achieve and do great things,” she said.

Izaak’s dad Jon Miller, 31, an engineer, said he doesn’t know where his love of learning came from — but just try to stop him getting bored.

“I teach children myself and the one worry for me, especially with boys, is that he doesn’t get bored,” he said.
