Understand the calculation

Formula and example

How it is calculated

For permitted fraction p and N sessions: at most ⌊Np⌋ absences. For a strict limit: at most ⌈Np⌉−1.

Worked example

For 20 sessions with at most 20% absence, four missed sessions are allowed. After two absences, two remain. A strict limit below 20% allows only three in total.

Things to check

  • The limit comes from your input. No national or institutional attendance rule is assumed.
  • Excused absences, partial sessions and make-up work are not automatically considered.

Frequently asked questions

Why do “at most” and “less than” differ?

At most includes the boundary itself. Less than excludes it. For whole sessions, this can change the allowance by one absence.
