The Absurd Pencil Test That Decided One’s Race During Apartheid

The “pencil test” is one of the most infamous and bizarre examples of how the South African apartheid government used “pseudo-science” to enforce racial segregation. It was a method used to determine whether a person should be classified as White or Coloured, or Coloured or Black.

What was the Pencil Test?

The test was exactly what it sounds like: an official would stick a pencil into a person’s hair and ask them to shake their head.

If the pencil fell out: The person was deemed to have “straighter” hair and could be classified as White (if they were on the borderline) or Coloured.

If the pencil stayed put: Their hair was considered “kinky” or “frizzy” enough to grip the pencil, and they were classified as Coloured or Black.

This wasn’t just a weird social experiment; it had devastating legal consequences. Under the Population Registration Act of 1950, your racial classification determined where you could live, what jobs you could have, and who you could marry.

The Coloured community was often the primary target of this test.

Because the Coloured community has a diverse ancestry—including European, Southeast Asian, and indigenous Khoisan roots—physical appearances varied widely even within the same family.

Family Splits: It was common for one sibling with lighter skin and straighter hair to pass as “White,” while another sibling was classified as “Coloured” because of the pencil test. This often forced families to split up to avoid legal trouble.

Re-classification: If someone in the Coloured community applied to be re-classified as White to get better rights, or if the government suspected a “White” person was actually Coloured, the pencil test was the “go-to” tool for officials.

The pencil test highlights how arbitrary the apartheid system was. There was no biological or scientific basis for it; it relied entirely on the subjective observation of a government clerk with a pencil.

The human impact: A person’s entire future—their right to vote, their education, and their dignity—could literally depend on whether a piece of graphite tumbled to the floor or stayed stuck in their curls.
