MRCPCH FOP and TAS: The Complete Guide to Format and How to Pass

MRCPCH, Membership of the Royal College of Paediatrics and Child Health, is the qualification that marks a doctor's progression through paediatric training in the UK, and it is widely sat by international paediatricians. The theory examinations are the written foundation of the membership, and Foundation of Practice (FOP) and Theory and Science (TAS) are the first two candidates typically face. This guide explains their format, what each tests, and how to prepare for a first-time pass.

What are the MRCPCH FOP and TAS exams?

FOP and TAS are two of the written theory examinations on the road to MRCPCH, set by the Royal College of Paediatrics and Child Health. Foundation of Practice tests the knowledge, understanding and clinical decision-making expected of a doctor entering core specialist paediatric training, while Theory and Science tests the basic scientific, physiological and pharmacological principles that underpin clinical practice, along with evidence-based practice. Together they build the knowledge base you will draw on in the later Applied Knowledge in Practice exam and the clinical examination.

MRCPCH FOP and TAS format and structure

Both exams share the same structure: 100 single best answer questions in a two-hour paper, machine-marked with no negative marking. Candidates often take both on the same day, with FOP in the morning and TAS in the afternoon.

• Foundation of Practice (FOP): 100 single best answer questions, 2 hours.
• Theory and Science (TAS): 100 single best answer questions, 2 hours.
• No negative marking, so every question is worth attempting.
• Set and administered by the Royal College of Paediatrics and Child Health.

Each question focuses on a single aspect, such as selecting a diagnosis, choosing a treatment, or identifying an organism, so the exams reward precise, applied knowledge rather than long reasoning. Because the College updates its regulations over time, confirm the current specification when you apply.

Who can sit FOP and TAS?

The theory exams are open to doctors with a recognised primary medical qualification, and candidates typically sit them in the earlier years of paediatric training. There is flexibility in the order in which the theory exams are taken, though sitting FOP and TAS earlier is common because they build the foundation for the later Applied Knowledge in Practice exam. Because eligibility and any documentary requirements are set by the RCPCH and can change, confirm the current criteria before you apply.

MRCPCH is achieved by passing the theory examinations, Foundation of Practice, Theory and Science, and Applied Knowledge in Practice, together with the clinical examination. FOP and TAS are the entry-level theory exams that establish the knowledge and scientific grounding you will build on. Passing them keeps your paediatric training progressing and prepares you for the more advanced Applied Knowledge in Practice exam and, ultimately, the clinical assessment. Treat them not as isolated hurdles but as the foundation of your paediatric knowledge.

FOP and TAS syllabus: where to focus

Foundation of Practice leans toward the practical knowledge and decision-making of everyday paediatrics, from common presentations to the recognition and initial management of the acutely unwell child. Theory and Science leans toward the underlying sciences, including physiology, pharmacology and the basic science relevant to paediatrics, along with evidence-based practice and statistics. A balanced plan covers both, with particular attention to the areas you find least comfortable, since the two exams together sample a very broad curriculum.

A realistic FOP and TAS study plan

Most candidates prepare over roughly three months alongside clinical work.

• Weeks 1 to 6: build coverage across both exams, working through the curriculum topic by topic, answering questions as you go and reading every explanation. Give deliberate time to the science and evidence-based-practice content that TAS emphasises.
• Weeks 7 to 10: consolidate through a question bank, logging weak topics and returning to them, and making sure your FOP and TAS preparation are progressing together rather than one lagging.
• Final weeks: sit timed papers of 100 questions to build pacing, review your analytics, and taper before the exam.

Common mistakes candidates make

• Letting one exam lag behind the other instead of preparing FOP and TAS together.
• Neglecting the science and evidence-based-practice content of TAS.
• Reading passively for weeks before starting question practice.
• Rushing the single-aspect stems instead of reading each carefully and committing to the best answer.
• Leaving questions unanswered when there is no negative marking.

What to expect on exam day

With 100 questions in two hours, you have a little over a minute per question, so keep a steady pace and do not linger on any single item. Because each question focuses on a single aspect, read the stem carefully, identify exactly what is being asked, and commit to the single best answer. Flag anything that stalls you and return with fresh eyes, and because there is no negative marking, make sure every question is answered. Practising under timed conditions makes this rhythm automatic on the day.

The best way to revise for FOP and TAS

Because FOP and TAS are entirely single best answer, a question bank mapped to the RCPCH curriculum is the most efficient way to prepare. Work in tutor mode, read the reasoning behind every option, and track your performance so you can see whether your science-heavy TAS topics are keeping pace with your clinical FOP knowledge. Working through a large volume of well-explained questions across both exams, to genuine understanding, is the most reliable route to a first-time pass.

Frequently asked questions

How many questions are in MRCPCH FOP and TAS?

Each exam has 100 single best answer questions in a two-hour paper, with no negative marking. Candidates often sit both on the same day, FOP in the morning and TAS in the afternoon.

What is the difference between FOP and TAS?

Foundation of Practice tests applied clinical knowledge and decision-making in paediatrics, while Theory and Science tests the underlying scientific, physiological and pharmacological principles and evidence-based practice.

Is there negative marking in FOP and TAS?

No. Both exams are machine-marked with no penalty for wrong answers, so you should attempt every question.

How do FOP and TAS fit into MRCPCH?

They are two of the written theory exams, alongside Applied Knowledge in Practice, and are taken with the clinical examination on the way to full MRCPCH. FOP and TAS build the foundation for the later exams.

How long should I study for FOP and TAS?

Around three months of consistent, question-led preparation suits most candidates, with deliberate time given to the science-heavy TAS content.
