Consequent upon the report by an Assistant School Inspector in 1847 that the education provision in the ecclesiastical parish of Wrexham was of a very poor standard, the Court of Chancery directed the Trustees of the Wrexham Parochial Charities to establish a School in Minera. The Trustees of the Wrexham Parochial Charities continue to provide funds for the maintenance and improvement of the School building.
Since its foundation in 1851 the School has undergone many changes and improvements.
The school was remodelled in 1989 when the classrooms used by the nursery and reception children were added. The most recent remodelling and upgrading began in 2006 and was completed by the summer of 2008. This provided additional teaching space for Key Stage Two as well as addressing disabled access issues.
In 2001, the school celebrated its 150th birthday and to commemorate the occasion a stained glass window was commissioned and was dedicated by the Bishop of St Asaph on 29th March 2001.
In 2026, Minera School celebrates it 175th Anniversary.
