Case study 1: A large training focused school cluster
Background
The first supernumerary teacher started working across the Cardiff cluster in April 2018,
with another nine teachers starting in September 2018 all were undertaking their NQT
(newly-qualified teacher) year, all successfully completed this by July 2019.
The management and delivery model adopted remained the same for both years of the
Project, with additional local authority funding supporting the absence management
procedures, this post has been the main point of contact for the supernumerary teachers.
A shared Outlook calendar was used to manage the teachers allocation between schools,
deployed by Fitzalan High School (the cluster lead school). The primary trained teachers
were allocated according to their skillset and the ‘best fit’ for a particular school, but if
another school needed cover there was capacity to be able to allocate a teacher. All
supernumerary teachers also received a booklet containing the procedures for each of the
primary schools. This positively impacted consistency across the cluster.

improvement plans, secondly

sickness.
One afternoon each week all
cluster teachers trained
together at Fitzalan High
School (the cluster lead
school).
Having consistency with the same people
worked well, the cluster schools were keen
to employ the cluster teachers. It worked
well because the cluster teachers mark
the work and deliver any follow up work’;
they liaise with the class teacher
‘whereas someone from an agency, would
just appear and go again’.
Training delivered
There is a strong teacher training ethos in the cluster lead school with training delivered
across the cluster; there are opportunities for NQTs and teaching assistants to lead
workshops or training in their area of expertise.
The cluster lead school is an NQT Aspire school, with a team delivering to primary and
secondary staff.
All supernumerary teachers participated in training every Wednesday afternoon at the cluster
lead school, this contributed to them feeling part of the school’.
The supernumerary teachers also participated in all the inset training at the cluster lead
school.
They have also been able to attend a range of CPD (continuing professional development)
opportunities offered by the cluster primary schools.
The most successful aspect of
the project has been the quality of
teaching and learning across the
phases, and standards as a
whole. (Cluster lead)

Strengths
Challenges
Training together means all supernumerary teachers
received the same message in terms of expectations,
and quality of teaching and learning and that has been
really impactful.
They all understand the new curriculum - the philosophy
behind it and how different schools are implementing it.
The supernumerary teachers have had opportunities to
share and collaborate with each other during training.
Training is regular and planned, and not ad hoc as
opposed to agency supply teachers who receive very little
training.
In order to provide
opportunity for
supernumerary teachers
to complete medium term
planning and
assessment, they
needed to be allocated to
schools on longer term
projects.

people you are going through
your NQT stuff together and
that wasn’t the case before –
you were on your own.

Case study 2: Special Educational Needs cover
Background
One supernumerary teacher started working across the cluster in Nov 2017. The teacher
completed their NQT (newly qualified teacher) induction during the first year of the Project.
The management and delivery model adopted remained very similar for both years of the
Project. The teacher provided cover for a long-term absence for four days at the cluster lead
school (Maes Ebbw School), spending the fifth day at the other cluster school (Ysgol Bryn
Derw) (the allocation was determined by the size of the schools). The supernumerary
teacher’s role at the cluster school varied; PPA (planning, preparation and assessment)
cover for the same class at the beginning changing to covering a range of classes for PPA
from Spring 2019.

and to allow for the expertise
of the cluster teacher to be
shared with more staff.
It has been possible to plan ahead with
the specific curriculum focus that is
needed, this has allowed the main
teacher to hand over some responsibility
for a particular subject area.
Contrasting staffing requirements between mainstream and Special schools
Agency supply teachers are not indemnified to be able to use
specific training qualifications such as ‘team teach, handling’
in the Special school. As a result there can be supply
teachers in classes unable to ‘move and handle’, even
though they are trained; this means there is more workload
on the other members of staff in the class.
Such an issue would not be so pressing for a mainstream
school, but for a Special school, there is a greater demand to
move pupils, toilet visits etc., such ‘demands on staff can be
draining’. In this cluster the supernumerary teacher has been
signed off by the headteacher to use such techniques, as she
is employed by the school.
The teaching assistants (TAs)
understand the routines and
systems better than an irregular
supply cover teacher would, with
the teacher needing to take the
lead from them as they know the
children. Unless a teacher is in a
classroom consistently as the
‘teacher’ in a Special school, the
teacher has to take the lead from
the TAs as they know the
children.
The young people have had a
massively good deal out of having
access to [the supernumerary
teacher]. This would not have been
the case with a supply, as [the
teacher] has planned for the future.

Staffing challenges
A teacher’s ability to ‘step in and click with a class’ is different in
a Special school. For example, the supernumerary teacher
spent a two week block at the other cluster school. There was a
negative impact on the pupils and class team at the cluster lead
school - it is difficult to explain the situation to the learners. A
more regular weekly pattern can suit learners better; with the
supernumerary teacher spending the same day each week at
the other cluster school, and the lessons delivered in their
absence by a Level 4 HLTA (Higher Level Teaching Assistant)
each week.
However, on the other hand consistency may not be as critical
as in mainstream, when there is only one adult in a class a
Special school class can have eight children and four adults, if
there is a change in the teacher there can still be a level of
consistency from the support staff.
‘The challenge for the sector is
knowledge of the individual
children and the knowledge of
the way a school works this is
more important than whether
you have a certificate that says
you are a qualified teacher.
Parents want to know that
someone who knows their child
and understands the needs of
their child is in front of their
child’.

Case study 3: A large cluster with a smaller number of supernumerary teachers
Background
There are two supernumerary teachers working in the Wrexham cluster. The cluster schools initially
looked at the number of children on role in each school in the cluster and worked out a percentage
allocation which equated to a number of days of supply cover to which each school was entitled per
term; there was some flexibility within this allocation. All of the NQT (newly-qualified teacher)’s
observations were completed in Ysgol Heulfan (the cluster lead school), where they were most
familiar with pupils and school policies such as behaviour management routines. Often, the
supernumerary teachers were used to release staff to focus on school-level priorities such as
professional development and particular projects. Some of the cluster schools have used the
supernumerary teachers’ time on a regular basis e.g. the same day per week. The supernumerary
teachers have also been involved in extra-curricular activities. The cluster finds that it is not
particularly practical to use the supernumerary teachers for sickness cover, which is too ad hoc. The
supernumerary teachers have been in high demand within the cluster.

Impact

An online calendar is used to book the
teachers’ time, with allocation roughly
decided by pupil numbers. Schools
tend to book their supply cover weeks
in advance and in most cases, the
teachers are used to release staff to
focus on school-level priorities such
as professional development and
particular projects. Some schools
book a teacher on a regular schedule.
Teachers are also involved in extra-
curricular activities.
The project has allowed cluster
schools to raise standards within
schools, focusing on school
improvement priorities to a
greater extent than they might
otherwise manage. The teachers
have built good relationships with
colleagues and have benefitted
from a wider range of professional
learning, observing good practice
and experience of extra-curricular
activities.
Making the most of available Supernumerary teacher time
For this pilot project, the cluster decided to trial employing two supernumerary teachers across the
eight schools. The schools judged this to have been correct for a pilot, but of course it has meant
that schools needed to ensure their limited time with the supernumerary teachers was used to best
effect. As such, the cluster schools have made sure they allow supernumerary teachers to deliver
meaningful lessons while providing cover. They have planned and delivered lessons across upper
Key Stage 2 and lower Key Stage 3, for example delivering weekly sessions on literacy, numeracy
and science. They have also been involved in extra-curricular activities; one has supported an after-
school football club and they have attended a residential course with pupils. They have also been
involved in Forest School and one has provided valuable support in the cluster lead school’s
resource provision. The supernumerary teachers were given two weeks of planning time at the start
of the project and in September 2018 to ensure they could deliver valuable lessons while providing
cover. Learners emphasised that they find the lessons just as enjoyable and that the supernumerary
teachers bring new teaching approaches, resources and games to the classroom.

Using cover for specific school improvement priorities
The supernumerary teachers have primarily been used to release staff to focus on school
development priorities. For example, using the supernumerary teacher cover:
For staff to work on a formative assessment project (run by the regional education consortium).
For staff to work on levelling pupils’ work and building portfolios.
To focus on monitoring of standards of pupils’ work and to monitor subject areas (it is usually
challenging for them to release staff for such activities). This school also noted that using the
supernumerary teachers in this has allowed them to continue to improve following an Estyn
monitoring period, focusing on developing pupil learning and raising standards.
To release middle managers, each of which have been allocated a priority from the School
Improvement Plan to progress during this non-contact time.

The greatest value of the project has been the
ability for school to regularly utilise [the teacher]
for internal moderation and standardisation of
work within school. This has allowed SLT
(school leadership team) and subject leaders to
continually monitor and raise standards of
teaching and learning.
The teachers know the pupils, staff and routines
of the school which help them to deliver lessons
effectively. Pupil behaviour has been better as
the teachers understand individual pupils’
needs; this has meant the pupils respond well
towards them. Teaching and learning in class
has remained at a high standard even when we
have to release teachers from their classes.

Case study 4: A Welsh-medium cluster
Background
The Neath Port Talbot cluster has piloted different ways of apportioning teachers' time over
the duration of the project. Initially, a specific apportionment was set aside for each school
but this arrangement did not respond effectively to the needs of schools as they arose.
Secondly, a flexible system of allowing schools to use teachers at short notice for the supply
of illness or emergency was piloted. This system caused a burden for Ysgol Gymraeg
Ystalyfera Bro Dur, which organised teachers' time. The cluster has now established a
process of apportioning teachers' time to support the schools' improvement plans (taking
into account a sensible number of days for each school). Ysgol Gymraeg Ystalyfera Bro
Dur’s bursar keeps records of the supply teachers' time. Cluster schools try to provide their
needs to the lead school a month in advance, and the bursary provides a fortnightly
schedule.
Overall, the supply teachers have worked across Key Stages. The current system has
allowed a good balance between the needs of schools and the needs of supply teachers
themselves.

The cluster has trialled
different approaches to
allocation, starting with an
equal and regular split
between schools, moving
to a completely flexible on-

then finally settling on
using the teachers to
support school
improvement priorities
across the cluster. The
teachers generally work
across key stages and are
allocated periods for
planning together.
Schools have used the teachers to release
staff to focus on school improvement, for
example collaborative planning for the new
curriculum. The teachers are familiar with
schools’ policies, approach and strategies,
including the Welsh Language Charter. The
project has provided consistent Welsh-
medium supply cover, which is often very
difficult to secure.
Usually, when you leave work for
supply teachers, it isn’t always
completed, or not to the standard you
want, and you have to re-do it this
hasn’t happened. (Translation)

Specific benefits for Welsh-medium
cluster schools
The Welsh-medium schools regularly face
challenges in recruiting suitable supply staff
through external agencies, able to teach
through the medium of Welsh to a high
standard. It is not uncommon for schools to
make use of non-Welsh speaking supply
teachers, when faced with a lack of other
options. Supernumerary teachers address
these supply challenges, ensuring schools can
access Welsh-medium supply regularly and
with less difficulty.
Supernumerary teachers are familiar with the
school’s Welsh-language policies, projects and
approaches. For example, they have been
able to work in-line with the schools’ Welsh
Language Charter strategy and adopt or
develop appropriate resources.
They have understood and supported the
school’s focus on Welsh language and literacy,
using the same drills and language formats as
other teachers. For example, one
supernumerary teacher reported that running
Speaking and Listening sessions with learners
was a specific performance objective for them.
Benefits the Project has offered to
supernumerary teachers
The teachers have received time for joint planning at the
start and end of term. During this time, they have
successfully created resources, shared teaching
methodologies and focused on school-level priorities.
The salary offered through this project is more stable than
the normal supply salary, though still less stable that a
permanent teaching post. Teachers benefit from the
status of being a teacher with permanent roles. They have
access to the training available for other teachers,
including specific courses on themes such as ASD
(autism spectrum disorder) and safeguarding in different
schools.
They have also been invited to join school communities,
participate in social events and create relationships with
co-workers. The early years of teaching can be very
challenging and feeling part of the community, and having
necessary support, has a positive impact on the well-
being of NQT (newly-qualified teacher) and supply
teachers.
They have been able to gain experience across different
key stages (for example, a secondary-trained teacher
gained some experience in Foundation Phase). They are
now ‘better teachers’, demonstrated through the
performance management processes.
