The mark system, developed by Alexander Maconochie, shifted the focus of penology from fixed sentences to a credit-based approach centered on reformation.

Under this system, prisoners were required to accumulate a specific number of marks proportional to the severity of their offenses to become eligible for release.1

Earning and Losing Marks

  • Earning Marks: Prisoners earned credits through consistent good conduct, diligent hard work, and engagement in study.1
  • Losing Marks: Marks could be denied or subtracted as a consequence of indolence or general misbehaviour.1

This method prioritized training and individual performance, marking a significant departure from traditional punitive models and laying the groundwork for modern practices like parole and indeterminate sentencing.1
