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 Exceptional

Pupils attend school regularly and behave to an exceptionally high standard. Pupils' attendance rates are among the best nationally, with remarkably low levels of persistent absence. The school’s uncompromising expectations, combined with highly effective work with families, ensure that any barriers to attendance are swiftly identified and removed. Pupils arrive punctually and settle immediately, enabling learning without delay. Behaviour in classrooms and around the school is exemplary. Pupils conduct themselves with maturity and respect, creating a calm and purposeful atmosphere in which everyone can thrive. Bullying and discrimination are not tolerated. Staff implement routines with unwavering consistency. Pupils are confident that any concerns will be addressed promptly and fairly. This high-quality behaviour is equally evident during social times.

p.2

Attendance and behaviour Exceptional

Where pupils face challenges with behaviour or attendance, highly skilled staff provide tailored, compassionate support that has a transformative impact. Pupils feel safe and valued, and their relationships with staff are highly positive. Leaders and staff uphold the same ambitious expectations for every pupil, reflecting their deep commitment to inclusion. These consistently high standards of attendance and behaviour, sustained over time, make a significant contribution to pupils’ academic success and overall wellbeing.

p.2

Achievement Strong standard

Pupils achieve very highly across the curriculum. This includes their foundational knowledge of communication and language, reading and mathematics. Pupils with special educational needs and/or disabilities also make rapid progress from their individual starting points across a range of subjects.

p.2

Achievement Strong standard

Pupils learn the curriculum extremely well. They build the knowledge they need to understand increasingly difficult topics. Pupils achieve highly in national examinations at the end of key stage 4. These results are well above national averages. The achievement of disadvantaged pupils at the end of Year 11 is impressive. Over the last 3 years, these pupils' attainment and progress have been above those of non-disadvantaged pupils nationally. This is a direct result of the work of the school to identify these pupils' needs and to ensure that they get the help they need to succeed. These pupils, along with their peers, are very well prepared for the next stage of their education, employment or training.

p.2

Curriculum and teaching Strong standard

Leaders have established a broad, ambitious and imaginative curriculum. It is carefully designed to meet the needs of all pupils and prepare them well for their adult lives. Leaders have a precise understanding of how effectively this curriculum is being delivered. They ensure that teachers are experts in their subjects. This expertise helps teachers to choose activities that take close account of pupils' individual needs. Creative and interactive teaching enables pupils to develop their critical thinking skills. Leaders rightly focus on supporting pupils to take ownership of their learning so that they can get the very most out of their education.

p.2

Curriculum and teaching Strong standard

All pupils access the same ambitious curriculum. Teachers demonstrate an excellent understanding of how best to adapt learning to support pupils' special educational needs and/or disabilities. Staff check pupils’ understanding regularly. This equips them to pinpoint and address gaps in pupils’ knowledge. Pupils respond to their teachers' feedback by improving their work. Teachers support pupils who are less confident in their communication or number skills very well. There is a clear focus in lessons on developing pupils’ vocabulary and their spoken communication. This successfully furnishes pupils with the skills they will need for future learning.

p.3

Inclusion Strong standard

The school places inclusion at the heart of its work, ensuring that pupils who face barriers to their learning can flourish. Leaders put the best interests of these pupils at the forefront of their decision-making.

p.3

Inclusion Strong standard

Leaders ensure that staff expertly deploy well-chosen strategies to meet the individual needs of their pupils. Leaders review this work carefully to ensure that it is effective. Pupils, parents and carers appreciate this support. Pupils with special educational needs and/or disabilities study the curriculum in equal breadth and depth as their peers. Leaders ensure that additional funding for disadvantaged pupils makes a positive difference to their learning.

p.3

Inclusion Strong standard

The school has high aspirations for what all pupils can achieve. Leaders work thoughtfully together to identify and tackle barriers to their success. This ensures that all pupils access and enjoy a huge variety of enrichment opportunities, despite any challenges they may face. These include activities such as the very popular Duke of Edinburgh's Award. As a result, disadvantaged pupils build their confidence and independence well.

p.3

Leadership and governance Strong standard

Leaders, trustees and governors share an ambitious vision for the school and its future. They systematically evaluate strengths and priorities for further improvement. Well-thought- out ways of managing the school's work and a keen analytical approach ensure they make wise decisions that put pupils’ interests first. Leaders at all levels are part of the school improvement journey. Leaders allocate appropriate time and support to all staff to be the best they can be. Trustees and governors are highly knowledgeable about their roles and hold the school to account appropriately. They have detailed knowledge of the school’s context. They embrace challenge and maintain the highest expectations so that all pupils can excel. Staff morale is high. Expectations about workload are manageable and fair. Staff know that their wellbeing is supported. Leaders offer staff a substantial training programme to develop

Personal development and wellbeing have a high priority at this school. Leaders provide a well-structured programme that helps pupils grow into confident, respectful and resilient young women. There is a distinct focus on pupils developing their thinking and discussion skills. Through the curriculum, pupils learn about fundamental British values and their relevance to modern life. Pupils have a secure understanding of important issues such as consent and the dangers of social media. The school promotes tolerance and celebrates diversity.

p.4

Personal development and wellbeing Strong standard

Pastoral care is a strength. Staff know pupils well and respond quickly to their needs. Specialist provision, including mentoring and counselling, makes a positive difference for pupils facing challenges in their lives. Pupils attest to the success of this support. Leaders offer a wide range of enrichment activities, clubs and visits. These opportunities help pupils develop confidence, teamwork and leadership skills. For example, pupils in Year 10 led their own assembly challenging gender stereotypes in different careers. Pupils engage positively in the school's broad enrichment offer.

p.4

Personal development and wellbeing Strong standard

Careers education is carefully planned. Pupils receive impartial advice and experience an increasingly wide-ranging offer of work-related learning. This includes visits from employers and successful school alumni. Post-16 students benefit from expert guidance with their applications to universities and apprenticeships. Leaders have thought carefully about how to raise the aspirations of all pupils, including those who are disadvantaged. The school’s approach ensures that pupils are well prepared for future academic success, as well as life beyond school.

p.4

Personal development and wellbeing Strong standard

Staff equip pupils with the knowledge, skills and character to thrive. Leaders are rightly proud of the extremely broad range of destinations that pupils progress to when they leave. They ensure that the school’s personal development programme is closely monitored so that it maximises all pupils’ experiences of school life.

p.4

Post 16 provision Strong standard

Leaders have a clear vision for the school’s post-16 provision. They have put in place a broad range of academic courses, personal development opportunities and enrichment activities. These opportunities help all students to make informed, ambitious choices for their futures.

p.4

Post 16 provision Strong standard

Students demonstrate mature study habits and produce sophisticated work in lessons. Leaders monitor students' progress closely. If students fall behind in their learning, staff act quickly to provide support, such as structured mentoring and study guidance. Leaders understand the strengths of their provision. Through their cycle of review and adaptation, students' average progress and attainment across their study programmes have improved year on year. Students achieve very highly in national examinations at the end of key stage 5.

p.4

Post 16 provision Strong standard

Through a well-designed and comprehensive careers programme, students are very well informed about opportunities for the next stage of their education, employment or training. Most students move on to an impressive range of university destinations. Opportunities such as public speaking and visits to lectures and conferences are highly effective in developing students' character and positive personal traits. Students remark on how much they appreciate the care and the opportunities that they receive from their teachers.
