A test taken in lockdown
The circumstances were ordinary and the result was not. Schools were closed, families were at home, and Kaur's parents arranged an assessment online. The reported figure was 145. The Week reported on 30 January 2021 that the four-year-old had joined Mensa; The Tribune carried the story the same month.
Mensa's admission standard is a score in the top two per cent of the population. At four, the child being tested cannot read a long paper, so assessments at that age rely on verbal and non-verbal reasoning administered individually, which is a different instrument from the supervised written test older candidates sit.
What a score at four measures
This is where care is needed, and where most coverage stops being useful. An IQ figure for a four-year-old is less stable than one for a teenager: young children develop unevenly, and scores taken at that age are known to move as they grow.
That does not make the result meaningless. It makes it a snapshot. The honest description is the one this page uses throughout: an IQ of 145 reported in January 2021, which qualified her for Mensa at four. It is also worth noting what Mensa membership is at that age: a society card and a reading list, not a school place, a bursary or a formal gifted programme, and nothing in these sources suggests she received any of those.
The family account
Her father, Sarbjit Singh, is a teacher, and her mother, Rajvinder Kaur, is a solicitor. The detail they gave reporters is the one that usually precedes these stories: she knew the alphabet at 14 months.
Her stated ambition at four was to be an astronaut. It is quoted here because it was published, not because it predicts anything. The coverage described her as a British Sikh girl and was carried widely in the Indian press, which is where both of the sources used on this page come from.
Where Dayaal Kaur is now
The record ends in January 2021. She was four then and would be around ten now, and nothing in these sources describes her schooling, her results or her activities since.
That gap is deliberate on this page. A child who made the news at four has no public life to report, and the responsible position is to publish the documented event and stop there.
What is documented and what is not
Documented: membership of British Mensa at the age of four in January 2021; a reported IQ of 145 from an online assessment taken during lockdown; her home in Birmingham; her parents' names and occupations; the detail that she knew the alphabet at 14 months; and her stated wish to become an astronaut.
Not documented here: her date of birth, the name of the assessment used, her school, and anything after January 2021. The birth year on this page is derived from her reported age at the time.
