Parents whose children skip school in Nottinghamshire are to face tougher measures.
The county council can currently fine parents £50 if children are absent from 50% of classes over eight weeks.
They now plan to issue the fixed penalty notices if children fail to turn up for a quarter of their lessons over a six-week period instead.
Education bosses said it was the responsibility of parents and carers to get their youngsters to class.
Fines of up to £100 are to be issued to parents of truants in Portsmouth under new powers adopted by the city council there.
The fines are enforced under the government's Anti-Social Behaviour Act introduced in 2003.
