A-Level Chemistry Tutors in Barnet 2026

A-level Chemistry in Barnet is a subject entered at 33 providers that DfE scored for value added in 2024/25, of which 29 carry a published figure and four are suppressed. Woodhouse College holds 216 of the borough's 894 matched entries, roughly one in four. Nine of the 29 published scores sit clear of the national average; the other 20 cannot be separated from it, and Barnet's four selective providers land in four different places on the table.

That last point is the one worth holding on to. Value added is not a measure of raw attainment: it compares the grades a cohort achieved against the grades students with the same prior attainment achieved nationally, so it has already taken intake into account before anyone reads it. A parent choosing between a grammar school, a sixth form college and a further education college in Barnet will not find the answer in the school type, because on this measure the borough's providers of each kind sit on both sides of zero.

Which Barnet providers enter A-level Chemistry, and where the entries sit

Barnet is its own local authority, code 302, so a sweep of the authority is a sweep of the borough. Thirty-eight Barnet providers appear in the 2024/25 dataset and 33 of them return an A-level Chemistry row. Twenty-nine carry a published value-added score. Four are suppressed, meaning the matched cohort was too small for DfE to publish a figure: Mount House School, St Andrew the Apostle Greek Orthodox School, The King Alfred School and The Totteridge Academy.

The entries are concentrated. Across the 29 published rows there are 894 matched entries, and Woodhouse College alone accounts for 216 of them. The five largest cohorts, Woodhouse with 216, The Henrietta Barnett School with 66, Queen Elizabeth's School, Barnet with 62, Mill Hill County High School with 62 and Ashmole Academy with 45, hold 451 between them, just over half the borough's total. The remaining 24 providers share 443 entries, and 15 of them have fewer than 20 each.

Those providers are not variations on one kind of school. Barnet's A-level Chemistry is taught at a standalone sixth form college in Woodhouse, at a further education college in Barnet and Southgate College, at independent schools including Brampton College, Mill Hill School Foundation and Menorah Grammar School, at a specialist 16 to 19 free school in Imperial College London Mathematics School, at faith schools including JCoSS, Finchley Catholic High School and Hasmonean, and at four providers recorded as selective. A borough-wide average across that range would describe none of them.

The table below is ordered by matched entries, largest first, because the entry count is what determines how much weight any single row can carry. Matched entries count only those students whose prior attainment DfE could match, so the figure is smaller than a department's total entry.

One qualification belongs with every figure in it. A value-added score is DfE's progress measure for a single cohort in a single year, and nothing more: it records how the 2024/25 leavers' grades compared with the national pattern for students who started from the same prior attainment. It is not a measure of teaching quality, and the order of the rows is not a ranking. A department can teach well and return a score that spans zero, one unusual year can move a figure that says nothing about the years on either side of it, and a score describes the students who were measured rather than the staff who taught them.

Sorted by matched entries, largest first, not by score; the order is not a ranking and the measure is not a measure of teaching quality.

What do Barnet's two largest Chemistry departments publish about their own courses?

Two Barnet providers set out their A-level Chemistry course in enough detail on their own websites to be worth reading before an open evening: Woodhouse College, which holds 216 of the borough's matched entries, and The Compton School, which holds the highest published score in the borough on 26. Both name AQA.

Woodhouse College's own Chemistry page publishes a full entry condition rather than a general sixth-form rule. For Chemistry it asks grade 6 in Mathematics and grade 5 in English Language, with 7 and 6 in Science Combined Trilogy if Chemistry is the only science taken at A level, or 7 and 7 if it is taken alongside another A level science, or 7 in chemistry with 6 in biology and 6 in physics for a student who sat the separate sciences. It also sets an expectation of a minimum of 5 hours per week of private study, which is a more concrete statement of workload than most providers publish.

The Maths grade in that list is not incidental. Woodhouse's own Chemistry page states that a minimum of 20% of the course involves maths skills, against 10% on its Biology page, which matches the national requirement DfE sets per science subject; our A-level Chemistry page sets out what that covers and how each board assesses it, including the separately certificated practical endorsement.

The Compton School publishes a different kind of detail: its curriculum page links directly to the AQA 7404-7405 specification, names the Common Practical Assessment Criteria, lists the topic structure of the course, and records that it has three A-level Chemistry teachers supported by a senior technician holding a Salters CLEAPSS national award. That is an unusually specific account of a department's practical capacity, and it is the kind of thing a parent can ask about directly.

For the remaining Barnet providers we found no exam board published on the pages we read. That is a statement about our search and not about those schools: a board may well be named in a printed course guide, in a sixth-form prospectus issued on request, or on a page we did not reach. The practical course of action is to ask the department which specification its students sit, because the answer changes which past papers are worth working through.

Confidence and progress

My son was low in confidence after COVID and the gaps in learning were building up. Using this service helped plug those gaps, rebuild confidence, and improve his ability to learn properly again.

Amazing tutors!

We arranged maths and English tuition ahead of GCSEs and both tutors were brilliant. My daughter's grades improved, and by results day she achieved two grades higher than in her mock exams.

Great Teaching and Focused Learning

I attended an English bootcamp with Leading Tuition and the experience was excellent. The teacher gave focused attention to the small group while keeping the lessons interactive and engaging.

Do Barnet's four selective providers score higher in A-level Chemistry?

No, and they do not score lower either. They land in four different places, which is the more useful answer. Four of the Barnet providers in the Chemistry table are recorded as Selective on their Get Information About Schools records: Queen Elizabeth's School, Barnet, The Henrietta Barnett School, St Michael's Catholic Grammar School and Mount House School. Between them they occupy every state the dataset allows.

Queen Elizabeth's School, Barnet returns 0.33 on 62 matched entries, with an interval of 0.05 to 0.62 that lies entirely above zero. The Henrietta Barnett School returns -0.50 on 66 matched entries, with an interval of -0.78 to -0.23 that lies entirely below it. St Michael's Catholic Grammar School returns -0.17 on 34, with an interval of -0.55 to 0.22 that spans zero and therefore settles nothing. Mount House School is suppressed and publishes no score at all.

This is what the measure is built to do. A value-added score compares a cohort's grades against the national performance of students who arrived with the same prior attainment, so a selective intake has already been accounted for before the figure is printed. A school that admits students with high GCSE grades gets no credit on this measure for those grades; it is scored on what happened afterwards. That is why selectivity does not read across to the score, and why four selective providers can sit in four different positions without anything being wrong.

The same is visible from the other direction. The highest published score in the borough is The Compton School's 0.87 on 26 matched entries, with an interval of 0.43 to 1.32, and The Compton School's record states an admissions policy of non-selective. So does Wren Academy Finchley's, at -0.49 with an interval of -0.95 to -0.03, which sits clearly below zero. Barnet and Southgate College sits lower still, at -0.66 from -1.14 to -0.18, and as a further education college its record carries no admissions policy field at all. Providers outside the selective group hold both ends of the published range.

One row deserves a note for how narrowly it misses. Imperial College London Mathematics School returns 0.61 on 12 matched entries, with an interval running from -0.04 to 1.26. The lower bound falls 0.04 short of zero, so on DfE's own test the score is not distinguishable from the national average, despite being the second highest point estimate in the borough. A reader who took the 0.61 on its own would draw a conclusion the interval does not support.

That pattern is the reason most of this table stays open. Interval width tracks cohort size closely across the borough: Woodhouse College's 216 matched entries produce an interval of plus or minus 0.155, while Menorah High School for Girls' 6 entries produce plus or minus 0.92, almost six times wider. Twenty of Barnet's 29 published scores span zero, and in the great majority of cases that reflects how many students were measured rather than anything about the teaching. The practical consequence for a parent is that for most Barnet providers the published Chemistry score is not a usable basis for choosing between them, and the provider's own published course conditions are.

How we tutor A-level Chemistry for Barnet students

We start from the specification the student is actually sitting rather than a generic A-level Chemistry syllabus, because the three boards divide the same content differently and set different papers. For a Woodhouse or Compton student that means AQA, with its three papers and its 12 required practicals; for a student elsewhere in Barnet it means establishing the board first, which is often the single most useful thing a first session produces.

The quantitative work gets its own attention. A student who is secure on the chemistry but slow on moles, rearrangement, logarithms in pH work or error and uncertainty calculations is losing marks that are entirely recoverable. We work those through on the student's own past papers rather than on generic maths exercises, so the practice looks like the exam they are sitting.

Practical work is handled differently again, because it is assessed by the teacher in the student's own laboratory and recorded as the course goes along, so it cannot be revised for the way a written paper can. What helps is making sure nothing is left outstanding late in Year 13 and that the student understands what each activity is demonstrating. Our tutors work alongside the school's own sequence rather than cutting across it.

Sessions are one to one and online or in person across the borough, and 91% of our students achieve their desired grades. We also support A-level Biology and Maths in Barnet, which matters where a student is taking Chemistry alongside another science: see our A-level Biology tutors in Barnet and A-level tuition in Barnet pages.
