St Joseph's Catholic High School

Address: Shaggy Calf Lane, Slough, Berkshire, SL2 5HW Unique reference number (URN): 143803

p.1

Safeguarding standards met

The safeguarding standards are met. This means that leaders and/or those responsible for governance and oversight fulfil their specific responsibilities and have established an open culture in which safeguarding is everyone's responsibility and concerns are actively identified, acted upon and managed. As a result, pupils are made safer and feel safe.

p.1

How we evaluate safeguarding

When we inspect schools for safeguarding, they can have the following outcomes:

p.1

How we evaluate safeguarding

Met: The school has an open and positive culture of safeguarding. All legal requirements are met. Not met: The school has not created an open and positive culture of safeguarding. Not all legal requirements are met.

p.1

Attendance and behaviour Strong standard

Pupils’ attendance is above the national average, including for disadvantaged pupils. Pupils are also consistently punctual to school and to lessons. Leaders carefully monitor attendance and quickly identify pupils who have barriers to regular attendance. Leaders work well with families in overcoming pupils' individual barriers. Pupils want to attend school because they enjoy being part of the school's positive, nurturing community. Pupils also enjoy the numerous enrichment opportunities that the school provides for them. Indeed, pupils show pride in attending the school.

p.2

Attendance and behaviour Strong standard

Leaders have created a calm environment around the school. Pupils are polite, courteous and highly respectful. Pupils develop positive relationships with staff, which makes pupils feel known and cared for. Pupils conduct themselves to a high standard and value their learning. In lessons, pupils follow instructions swiftly, listen attentively and want to do their best. Staff apply the school's behaviour policy fairly and consistently. As pupils move through the school, they manage their own behaviour with increasing maturity. Pupils reflect on and learn from their behaviour. Staff support pupils to build resilience. Pupils with special educational needs and/or disabilities are supported, through appropriate adjustments when needed, in meeting the school's expectations of pupils' behaviour. Bullying is rare. Incidents of bullying and discrimination are dealt with quickly and effectively.

p.2

Achievement Expected standard

Pupils achieve well in their GCSE examinations. The school's key stage 4 outcomes are above or broadly in line with national averages. Pupils make effective progress, particularly pupils who begin school with lower starting points. Disadvantaged pupils typically achieve more highly than their peers nationally. Pupils with special educational needs and/or disabilities (SEND) typically achieve well from their differing starting points.

p.2

Achievement Expected standard

Sixth-form students achieve below the national average in A levels, but closer to the national average on vocational courses. Typically, sixth-form students are well prepared to progress on to their next steps in education, employment or training.

p.2

Achievement Expected standard

Pupils develop their reading skills so that they can access the curriculum and read fluently. This includes pupils with SEND, who receive the support they need. Leaders identify gaps in pupils’ mathematical knowledge and older pupils are provided with additional interventions. Leaders know that there is further work to do in developing pupils’ writing, especially their accuracy.

p.2

Curriculum and teaching Expected standard

Pupils study a broad and ambitious curriculum. Leaders have identified the important knowledge that pupils need to learn. The curriculum sequences this important knowledge well so that pupils can build their knowledge effectively over time.

p.3

Curriculum and teaching Expected standard

Leaders have a clear understanding of the quality of teaching and know where improvement is needed. Teachers give clear explanations and help pupils remember what they have previously learned. Pupils who have special educational needs and/or disabilities (SEND) access the same curriculum as their peers. However, sometimes teachers do not provide pupils with SEND with precise-enough adaptations to the curriculum or teaching.

p.3

Curriculum and teaching Expected standard

Leaders identify pupils who need additional help with their reading. These pupils are given effective support to become fluent readers, including support with phonics. Leaders also identify pupils with gaps in their mathematical knowledge. Typically, additional support for mathematics occurs at key stage 4. Generally, teachers address pupils' inaccuracies in writing as pupils progress through the school. However, leaders know this needs to be sharper and more consistent.

p.3

Curriculum and teaching Expected standard

Teachers have secure subject knowledge. Generally, teachers check pupils’ understanding and address pupils’ misconceptions when they arise. However, sometimes teachers do not recognise gaps in pupils' knowledge and understanding. As a result, sometimes pupils do not develop a deep and coherent enough body of knowledge.

p.3

Inclusion Expected standard

Inclusion is at the heart of the school. Leaders have an unwavering dedication to addressing the academic and social barriers to achievement that pupils may face. Pupils are well known at the school and feel a sense of belonging. Leaders work closely with families and professionals to put pupils’ interests first. Staff provide well-considered and effective pastoral care for pupils.

p.3

Inclusion Expected standard

There are high aspirations for what all pupils can achieve. Typically, pupils with special educational needs and/or disabilities, alongside those known or previously known to social care, do very well in their examinations at GCSE. Leaders quickly identify pupils' needs and share relevant information with staff, including about appropriate strategies to meet pupils' specific needs. However, there is some variability in how effectively staff employ these strategies in the classroom.

p.3

Inclusion Expected standard

Leaders' use of funding for disadvantaged pupils is well considered and appropriate. The school prioritises the participation of disadvantaged pupils in enrichment activities, and disadvantaged pupils achieve above the national average. However, leaders' evaluation of the impact of this funding on the opportunities and experiences of disadvantaged pupils, including with regard to alternative provision, could be more rigorous.

p.3

Leadership and governance Expected standard

Leaders have an acute understanding of the context of the school and of the community that they serve. They share a clear vision for the school with governors and trustees. Leaders know the school's strengths and the school's areas for development. They select improvement priorities with pupils’ best interests at heart. Leaders build staff expertise through coaching and align evidence-informed staff professional development to the school's improvement priorities. The trust provides the school with additional training for staff and opportunities for wider staff collaboration.

p.4

Leadership and governance Expected standard

Trustees and local governors work in close partnership and share information effectively. They are clear about their roles and provide robust challenge and support in equal measure to school leaders. Trustees ensure that the school's statutory duties are met.

p.4

Leadership and governance Expected standard

Staff are proud to work at the school and feel valued by leaders. Staff's workload and wellbeing are taken seriously by leaders. Leaders ensure that staff workload remains manageable at times of change to policy and practice. Staff understand the need to support leaders in implementing school improvement initiatives, although they note the increase in what is asked of them. Staff feel respected by senior leaders for the work they do in supporting the school's improvement.

p.4

Leadership and governance Expected standard

Leaders and staff are tireless in their work to ensure that pupils have a successful education. Parents and carers are positive about the care given to their children, and many parents recognise the significance of the school’s work on pupils' lives.

p.4

Personal development and wellbeing Expected standard

Provision for pupils' personal development is a significant feature of school life. The school's personal development programme is informed both by the school's values and leaders' mission to promote pupils' self-belief. Staff support pupils' personal development through effective pastoral support that builds pupils' confidence and resilience.

p.4

Personal development and wellbeing Expected standard

Leaders have developed an extensive offer of enrichment activities that enables pupils to explore and develop their talents and interests. The programme includes a range of sports, alongside other activities such as Latin, chess, candle making and crochet. Pupils can also take part in The Duke of Edinburgh's Award. The school encourages pupils to serve the local community, engage with charity events and take pride in their accomplishments. Pupils take part in events to promote cultural awareness and visit different places of worship. While many pupils benefit fully from these enrichment opportunities, leaders could track participation more effectively and provide more targeted opportunities for some pupils, including disadvantaged pupils.

p.4

Personal development and wellbeing Expected standard

Personal, social and health education (PSHE) is taught through tutor time, assemblies and workshops. Pupils build a secure understanding of the fundamental British values. Pupils learn how to keep themselves safe, including online. All pupils receive age-appropriate relationships and sex education, including in the sixth form. Pupils learn about consent and the protected characteristics. Staff support pupils with special educational needs and/or disabilities to access PSHE lessons so that they can benefit from this important part of the school's curriculum. The school provides pupils with appropriate careers education, advice and guidance. Pupils learn about different career pathways, including apprenticeships, university and employment. Pupils attend talks from employers and training providers that help them to understand their options and inform their decisions about next steps. Leaders are working

p.4

Personal development and wellbeing Expected standard

on expanding their career provision, including providing work experience opportunities to further ready pupils for their next steps.

p.5

Post 16 provision Expected standard

The sixth form has grown substantially over the last few years, and leaders have developed an ambitious post-16 curriculum that includes both academic and vocational courses. The curriculum meets students' different needs and interests. Leaders review the curriculum regularly to ensure that it is providing students with an appropriately sequenced body of knowledge and skills across subjects. Leaders have identified where subjects need further development.

p.5

Post 16 provision Expected standard

Teachers are subject experts and generally explain new concepts clearly. Students are given the support they need to secure their learning and understand how to improve their work. Students take their studies seriously and develop positive study habits. Typically, students achieve more highly in vocational qualifications than A levels, where they achieve below their peers nationally. However, students achieve qualifications that enable them to move on to their chosen next steps in education, training and employment. Indeed, their next steps are informed by careers talks and a careers fair .

p.5

Post 16 provision Expected standard

Students enjoy an inclusive sixth-form learning environment and receive effective pastoral support from sixth-form staff. Relationships between staff and students are warm and respectful. Many students take on leadership roles or mentor their younger peers. Students take part in a range of enrichment activities and benefit from an age-appropriate personal development programme. At times, students could be further encouraged to develop their confidence and independence through deeper discussion about important issues in society.

p.5

What it's like to be a pupil at this school

The school is ambitious for its pupils. It provides a nurturing environment in which pupils feel safe and can develop and grow. Leaders have established a welcoming and caring community that prioritises pupils' wellbeing and achievement. Pupils rise to the expectations that the school sets for them. Pupils achieve well and are prepared for their next steps because staff support both pupils' academic and personal development.

p.5

What it's like to be a pupil at this school

Leaders work hard to help unlock pupils’ talents. Pupils enjoy an enriched curriculum with an array of opportunities to explore and deepen their learning. Pupils take part in competitions, workshops, events and the ‘electives’ enrichment programme. These activities help pupils to develop their interests and build empathy for others. The school encourages pupils to take leadership roles, and sixth-form students mentor younger pupils. Leaders have built a school community that fosters respect and kindness. Pupils thrive because they feel safe, cared for and included. Staff work together to support and care for pupils who may have barriers to their learning or wellbeing. Pupils follow well- established routines and instructions swiftly. They have positive relationships with staff. Conduct around the school site is calm and purposeful. Behaviour in class is highly conducive to learning. The school does not tolerate bullying and discrimination. If bullying or

p.5

discrimination happen, leaders deal with these effectively. Pupils attend very well and enjoy their time at school.

p.6

What it's like to be a pupil at this school

Leaders provide a balanced and broad curriculum. Teachers ably support pupils to develop their knowledge and skills. Leaders understand pupils’ barriers to learning well. Generally, pupils achieve well, especially in GCSEs. While some adaptations and adjustments could be further improved, disadvantaged pupils achieve highly. Students in the sixth form secure the qualifications they need to progress on to their next steps in education, employment or training.

p.6

Next steps

Leaders should strengthen how teachers check pupils’ understanding so that misconceptions are addressed more precisely, and that they deepen pupils’ knowledge, including when teaching the personal development curriculum. Leaders should build on their approach to pupils’ writing so that expectations are high across the curriculum and pupils consistently develop the accuracy of their writing skills. Leaders should ensure that the adaptations and adjustments pupils need are consistently in place to a high standard so that they develop their learning to the depth that they are capable of. Leaders should further support sixth-form students’ readiness for their next steps, through both the progress they make and through their personal development programme in making them resilient and confident.
