The parents of two pupils at Sir Harry Smith Community College in Whittlesey have been fined for failing to ensure their children regularly attended school.
One admitted the charge when she appeared before Peterborough Magistrates and was fined £150 with £150 costs and ordered to pay a £20 victim surcharge.
The other did not attend court but was found guilty in her absence and fined £400 with £150 costs and a £40 victim surcharge.
Neither parent can be named for legal reasons.
Jonathan Digby, Principal of Sir Harry Smith Community College, said: “Children need to go to school. If they are not in school, they will not learn and then fail to reach their potential. The courts play an important role in ensuring parents take their responsibilities regarding school attendance, seriously. Schools work closely with parents to help them do their best but sadly in some cases court action like this is necessary in the best interests of our young people.”
