Development: The Second Curve

This happens at the start of every year.  I half-write a journal entry and then something else note-worthy happens, I begin another entry and I neglect to complete both.  The result is either a huge single entry full of items, or three shorter entries in close succession (surely much preferred).

Grab a coffee/chardonnay/small dog and read at your convenience. 


Dear Journal

Has the year begun well?

Is our events calendar full, fun and shared?

Are the staff focused, trained, motivated and equipped for the year ahead?  

Is the new timetable working?

Are Friday Afternoons running smoothly?

It never fails to astonish me how different two adjacent weeks can be as the summer closes and a new school year begins.  From a peaceful planned period of completion of the Estate works at the end of August, to the high energy of a now-major, year-opening festival and the full influx of hundreds of fresh and refreshed faces.

To see Cransleyfest in full flight: lights dancing on the Hall; guests dancing on the lawn; fireworks dancing in the eyes, allows me a moment to take stock of the school’s ever progressing development, as it begins the academic year.  That moment to take a long breath before the show begins.

I watched this time with a more critical eye after five iterations of the event, and concluded - rightly or wrongly (someone will eventually let me know) - that the festival itself is still engaging for all ages, entertaining, well-timed and worth holding.  

Note to self, to speak to the team who sorted the weather…


The Cransley events calendar (see the schoolbase portal or Mr Morris’s recent email) is packed full of more and more occasions, for pupils and parents alike with every year that goes by.  And as a result this term tends to sweep by in a blur.  There is not a week that goes by without a major event taking place in school - from Head’s coffee mornings, parents evenings, ISA Art exhibitions, promotional filmmaking, guest speakers, trips and activities out of school, Harvest, Fireworks and Christmas festivals and productions and services, Open days, open afternoons, makers’ markets, occasions when we are hosting both Mr Morris’s Association of Junior Independent Schools and my group of fellow ISA Headteachers in the North West,  and much more.

My colleagues and I recognise that being a Cransley family is as much about a sense of experience and opportunity as it is about anything else.  I hope we meet that brief.


As employees of the school, we are part of a truly talented group of colleagues, each ever-increasingly expert in their field.

The year began with two intense training days for staff on mandatory safeguarding and child protection, our next careful but confident strides in the development use of AI in teaching and assessment, some exemplary pedagogical research, a wider sector overview and my outline development curve for the year ahead.  

If you are unlucky enough to find yourself talking with me at a Head’s coffee morning, I might chunter on about Sigmoid Curve theory, which describes a common life cycle pattern of growth, maturity, and decline, observed in various systems like businesses, products, technologies, and even individuals. 

If you haven’t encountered such a dull conversation topic before, it's an S-shaped concept curve that begins slowly, then enters a period of rapid, almost exponential growth, followed by a slowing growth rate as it approaches a plateau of maturity or saturation.  It can model projects, physical and mental activities, even relationships.

Sigmoid Curve Theory 1

A crucial aspect of the sigmoid curve theory, especially in business, is the concept of the "second curve" (yellow dotted curve above) which must be identified and started before the first one peaks, not once it is in decline (brown dotted curve).

The second curve initiates by recognising slowing growth from a previous curve, and the need for something new.  Progress isn’t immediate, because everyone gets twitchy - no one likes change and people love WhatsApp. Problems have to be predicted and addressed, plans have to be fail-safe and accurate, even when based on soft data and theory.  Time and effort and thought and collaboration is required.

Then, after this, when everything is readied, the change takes place and everyone starts to see the benefit of why the second curve was bought in in the first place.  Eventually these benefits become appreciated and normalised.  Everyone settles in, and growth is allowed to happen. 

Sigmoid Curve Theory 2

Having been the headteacher now for over nine years, and deputy prior to that, there have been hundreds of different curves which together have led to the school’s continued development - pedagogically, financially, operationally - and a school of our size is more flexible and adaptive than many other larger schools in bringing about those changes successfully.  

The latest major Sigmoid curves, amongst others are the development of AI in teaching and learning practice (more of which will be shared in another journal post) and the new timetable.

We may still be coming out of the ‘uncertainty’ stage, but we can see the reality backing up our theory, and that the decision was the right one.  Talking to parents and pupils and colleagues, even seeking out those who objected a few months ago, we can see that the benefits are being recognised and appreciated: Pupils don’t really notice the longer day, but teachers appreciate the increase in teaching time, and both feel that the Friday afternoon is a happy reward.  We know that the Friday lunch service is being fine tuned and we will better ourselves with every week.  If we are still making the mistakes in November, then complain.  I am right here, and ready to listen.

I would love for other schools, and their staff and pupils, to follow suit, and reap the benefits (and they are indeed asking) but to be frank, they all are far too large and rigid to move on such an idea.  Our agile, aspirant and flexible nature makes Cransley true pioneers in doing this.

Enough for now.  You have finished your cup of tea and I am heading home.

Yours, as ever

Mr Pollock

GCSE Results 2025

Dear Parents and Families

Congratulations to our 25 wonderful Year 11 pupils for the commitment and effort shown in their GCSEs.

35% of all exams results were graded 7 to 9 (compared to 23% nationally).  92% of exams results were graded 4 to 9 (70.5% nationally) and 88% of pupils have gained five or more GCSEs at 9-4.  

A fitting outcome for those pupils taking advantage of the continuing superb support and engagement from teaching staff, hard work and discipline and maximising their use of our pastoral provision.   

My colleagues have been exceptional in their teaching and support of our wide range of pupils across all subjects.  I am truly proud of everyone.

As usual, we are very pleased that many pupils have achieved well above their indicative grade (based on cognitive tests taken on entry into the senior school), some almost an average of three grades per subject, resulting in the pleasing number of top grades (7-9), mentioned above. 

It is rare that individual pupils are identified in our communications, however a particular mention is required for one pupil who attained seven grade 9s, one grade 8 and an A* in their A level maths last week. Furthermore, two other pupils achieved grade 8s and 9s in eight of their GCSEs taken and a fourth pupil achieved all grade 7/8/9s in all nine of their subjects.

As always, our benchmark is with other similar semi-selective intake schools across the country, and our initial findings are that we are higher than these settings and very much higher than national averages.  Further regional and national data is published over coming weeks.

Our pupils now enter into various colleges across the region, from schools to sixth form colleges, to study a variety of academic and vocational courses.

We will miss them dearly, and wish them every success.

Preparing for a new voyage (and other unnecessary nautical metaphors...)

Dear Parents and Families

The good ship Cransley is preparing for a new voyage, having dry-docked for a few weeks, had a good lick of paint around its hull, some adjustment and repairs to the rigging and trim and is looking rather fine.  The crew are returning this week for navigational information and direction, each fine, fit and fair, and we are very much getting ready to set sail, with our cargo in a couple of weeks time.

Before I lose the already-tiresome nautical metaphor, allow me to share some notices from the ship’s log:

GCSE Results 2025

We look forward to sharing our GCSE results tomorrow with our departing Year 11s before they navigate their journey to college and beyond, and I will write to inform you of all of the key headlines in the afternoon.

We know already about one astonishingly hard-working and able pupil who achieved an A* in their A level Maths last week, following his early taking of his Maths GCSE last year.  Huge congratulations to them.  I gather they started studying their A level Biology over this summer… just for fun.

Decoration and refurbishment

Our dutiful estate team, led by Mrs Holt and Mrs Totterdell-Lambert, have overseen a number of elements of R&R, including the painting of the ground floor of the Belmont Hall, notably the Entrance Hall, English room and Head’s Study (images below) in a beautiful heritage chalk white, enhancing the stunning Rococo plasterwork, and some ground work to the area outside of the Pavilion incorporating a new EYFS sheltered area and decking.  We have also prepared the ground for some new column lighting around the courts in readiness for the winter.

The old textiles room has now been converted into a Junior classroom (for Year 5) and some other repairs and restoration has taken place in other classrooms.

Our extensive project to refurbish the deteriorating windows of the Hall has been part-completed with the rear ground-floor windows replaced, and three of the front curved sash windows carefully removed for profiling and replacement.  We aim to complete the work by the end of 2026.

Autumn Open Day

We have chosen to postpone our Autumn Open Day from 20th September until the 4th October so as to not clash with other local independent schools, and I ask that you note the new date as we will require some of your children to be ambassadors for our visiting guests.

Please do share this information with the friends and families that you like, and certainly we welcome Year 5 and 6  parents taking the opportunity to see the Senior school in all of its glory.

Senior and Junior School Parent Handbooks

Parents asked us a few years ago for a document that contained all of the necessary information for the start of the year in one place and we have dutifully obliged, therefore can I insist that you read them carefully.  They were sent in a recent email from the School office and available on our website.

Junior School

Senior School

They contain further information about the new school day times, homework, uniform, pick up and drop off and much more.   They are about one cup of tea’s worth of essential reading (plus two biscuits).

Uniform

These children grow quickly, and if you can, please find time to dig out their uniform and try them on for size.  If you need new items, I recommend before running desperately to Monkhouse, that you visit our online pre-loved uniform website run by brilliant parent volunteers, where all proceeds are returned straight into the school (and have paid for several new interactive whiteboards and a school trip! Any clean good quality used stock should please be bagged and sent to the office for resale.

That’s it for now.  More tomorrow.

Yours, as ever

Mr Richard Pollock
