School history

The two Lewis schools trace their history to the will of their founder, Edward Lewis, a wealthy aristocrat, who traced his ancestry to Gwaethod Fawr, Prince of Cardigan in the tenth century.

Despite his privileged upbringing, Edward Lewis was mindful of the poverty and deprivation in the lives of ordinary people, and so, in his will of 1715, he made provision for the education of "fifteen poor boys". It is believed that by 1853 the foundation catered for the education of girls, but at an elementary level only.

In 1882, the Gelligaer School Board decided that a secondary school for girls was a necessity, and eventually, the School Board offered a room, the West Room, at their infants’ school at Pontlottyn. It was opened on 2nd February 1883 with Miss Emma Edwards as headmistress. Forty girls attended; twenty-one having free places.

Very soon the school became overcrowded and in 1896 a new building was handed over and became the Gelligaer Intermediate School for Girls. Again, this soon proved to be inadequate and on 1st November 1900 the school moved to a new building in Hengoed and was known as Hengoed Intermediate School and later as Lewis Girls' School. In 1959 the school transferred to its present site in Ystrad Mynach and in 1973, comprehensive education was introduced.

In the 1970s a new building was constructed in order to improve the facilities. Further major building projects were completed in July 1993 and March 2007. These developments have enabled all our students to be accommodated on one site and provide up to date facilities for the teaching of Languages, Science, Information Technology and Business Studies.

We have developed our facilities to provide a 21st Century education for our students. ICT resources are good. We have fully equipped computer rooms and 2 additional open access computer rooms for dedicated Sixth Form use. We have a specialist nurture provision for vulnerable pupils in ‘Ty Croeso’, (Welcome House), set within the school grounds.

Other major facilities include specialist rooms for a variety of subject. The School Hall is equipped with sophisticated lighting and sound systems for drama productions. There is a large gymnasium and the school has exclusive use of the local sports centre during the school day. Extensive playing fields, an artificial turf all-weather pitch, tennis and netball courts ensure that pupils have access to excellent sporting facilities. Investment in the site has been a priority for the last three years and internally the fabric of the school is of a very high quality.

The main building is fully accessible with the school actively implementing its Equality Action Plan to be as increasingly accessible as the budget allows.


Visions and values

School's Aims and Objectives

The sole purpose of Lewis Girls’ school is to ensure teaching is to the best possible standard so that pupils can engage with the 4 core purposes of learning to become:

  • Ambitious, capable learner.
  • Healthy, confident individuals.
  • Ethically informed citizens.
  • Enterprising, creative contributors.

Lewis Girls’ School is committed to safeguarding and promoting the welfare of children and young people and expects all staff and volunteers to share this commitment.


Mission Statement

I expect staff, and learners, to know what our school stands for so that ‘HEDD’ is lived here on a daily basis in our school.

 Mission Statement

Lewis Girls’ aims to be a happy, caring school, committed to creating an excellent learning environment where every student has the opportunity to achieve their potential.



We have core beliefs and values based on:

People: our best assets are our people - people focused on children learning and succeeding.

Diversity: we value each individual and protect their freedom and choice. We work against discrimination and support equal opportunities. We teach that with rights come responsibilities, to the environment and others.

Equity: Wellbeing and Inclusion: we are committed to providing an environment that supports the needs of all learners. We believe in honest, open and respectful relationships.

Partnership: we believe that achieving excellence in education is the outcome of partnership between parents, pupils and the community of partners.

Fun: we believe people work hard and learn best when they enjoy what they do.

We believe these values are achieved through teamwork, distributed leadership and excellence in education.


Pastoral Care

The school has a very strong pastoral system based on Heads of Achievement leading support teams, including form tutors. The aim is to guide and support students in their learning and provide advice and support for emotional problems and to ensure that progress, care and discipline is maintained. We pride ourselves on the care given to students, encouraging them to share their problems and seek support from staff if they need help.

A key role is that of the form tutor. They regularly link with parents to provide an immediate point of contact. The form tutors work with Heads of Achievement (H.O.A.) assigned to each Key Stage. These staff are supported by Assistant Heads of Achievement, progress managers and learning mentors to oversee the wellbeing of all pupils within the school.

Parents are encouraged to contact school if they have concerns regarding either academic progress or personal issues. These will be followed up and support provided to the pupil to help overcome any difficulties.


About our school

Lewis Girls' is an 11-18 comprehensive school and currently has over 720 pupils. The staff is well established and committed to the achievement of high standards and to the provision of a wide range of extra-curricular activities. Staff development has a high profile and the school is continually improving.

The school has an impressive record of success in academic, sporting, musical, cultural, charitable, enterprise and social activities extending over many years. In 2018, 16.9% of our Year 11 pupils achieved at least 5A*/A grades in their year 11 exams. The school is well disciplined, but friendly, and the quality of staff-pupil relationships is excellent. All pupils are encouraged to give of their best and expectations are high.

The school is situated in Ystrad Mynach but its pupils come from a catchment area of approximately 40 square miles. Close links exist between Lewis Girls', Lewis School Pengam and our feeder primary schools. In addition, a significant number of pupils attend the school from out of the catchment area as a result of parents exercising their right of choice of school.

We have strong links with our three neighbouring schools (Heolddu, Lewis Pengam and Rhymney) and Coleg Y Cymoedd. These links enable a reciprocal broadening of subject choices for all 6th Form students in the four schools. Many students travel to and from our school accessing a wide range of subjects within the Consortium.

The school is maintained by Caerphilly County Borough Council.

The Governing Body of the school numbers twenty and includes representatives of the L.A., parents, teaching staff, business and the local community.

Our Chair of Governors is: Mr James Grashoff
