14.2 The Written Exams: Format, Blueprint & Technique
Key Takeaways
- Trainer-published specifications put the Barista Skills written exams at 20 questions in 22 minutes (Foundation), 35 questions in 37 minutes (Intermediate) and 30 questions in 32 minutes (Professional), roughly one minute per question at every level.
- The pass marks published by the SCA are 60% at Foundation, 70% at Intermediate and 80% at Professional, meaning a Professional candidate may drop only about six questions out of thirty.
- Every written question maps to one of the SCA's published Barista Skills subject areas, which repeat across all three levels with increasing depth.
- Manual pour-over brewing, cupping-form scoring and green-coffee grading are not Barista Skills subject areas, so revision time spent on them earns no written-exam marks in this module.
- The highest-yield revision is numeric recall: 9 bar, 92–94°C brew water, 25–30 second shots, a 1:2 ratio, 18–22% extraction yield, 1.15–1.45% TDS, 60–65°C milk, and the 55 g/L Golden Cup brewing ratio.
14.2 The Written Exams: Format, Blueprint & Technique
Quick Answer: Each Barista Skills level has its own online written exam. Trainer-published specifications put Foundation at 20 questions in 22 minutes (pass 60%), Intermediate at 35 questions in 37 minutes (pass 70%), and Professional at 30 questions in 32 minutes (pass 80%). Roughly one minute per question means there is no time for deliberation — the papers reward recall of specific numbers and definitions rather than reasoning from first principles.
The pass marks are published by the SCA itself in the Coffee Skills Program course catalog. The question counts and time limits come from Authorized SCA Trainers' published course specifications; confirm the exact figures with your own trainer when you book, since delivery details can vary.
The Papers at a Glance
| Level | Questions | Time | Minutes per question | Pass mark | Practical |
|---|---|---|---|---|---|
| Foundation | 20 | 22 min | ~1.1 | 60% | none |
| Intermediate | 35 | 37 min | ~1.06 | 70% | 40 min, 3 sections |
| Professional | 30 | 32 min | ~1.07 | 80% | 95 min, 4 sections |
Note what the arithmetic means. At Foundation you may drop 8 of 20. At Intermediate you may drop 10 or 11 of 35. At Professional you may drop only 6 of 30 — a single careless misreading is a meaningful fraction of your margin. The step from Intermediate to Professional is a step in precision, not only in difficulty.
The Content Blueprint
The SCA publishes a topic overview for Barista Skills. Every written question maps to one of these subject areas, and the areas repeat across levels with increasing depth.
| Subject area | Foundation | Intermediate | Professional |
|---|---|---|---|
| Coffee Beans | Arabica vs robusta; freshness; roast degree and taste | Arabica varieties; origin and processing on flavour; roasting on solubility and density; degassing | Density, variety and cultivar; processing methods; decaffeination; packaging, storage and freshness |
| Workspace Management & Workflow | Grinder and machine components; safe use; a clean, organised workspace | Equipment and accessories layout; working in pairs | Drinks production |
| Espresso Process | Espresso recipes; grinder calibration and dosing; distribution and tamping | Grinder models and burr types; dosing, distribution and tamping techniques | Consistency of dosing, tamping and waste; grind particle distribution; tamper and distribution tools |
| Extraction & Brewing | What is espresso; the barista routine | Brew ratio calculation and the espresso brew formula; strength and extraction; refractometer use; brew recipes on flavour and body | Espresso machine; temperature and pressure on brewing; boiler and pressure systems; designing brew recipes; espresso blend construction; extraction measurement tools |
| Sensory | Espresso extraction and descriptors | Extraction rates of different compounds and flavours; body and texture of espresso; the SCA Flavor Wheel | Organic acids; sensory evaluation; optimum balance of multiple coffees; milk's effect on coffee flavour |
| Milk | Freshness; foaming and temperature of steamed milk | Composition and deterioration; foam quality and stability; milk substitutes; steaming technique and the SCA foam standard; SCA latte art standards | Composition and processing; foam creation, quality and stability; milk quality and ability to foam; factors affecting milk quality; proteolysis and lipolysis; coffee acidity's effect on milk; heat's effect on milk; SCA foam and free-pour latte art standards |
| Espresso-Based Menu | Drink components and construction | Espresso-based construction and taste differences; preparing multiple beverages correctly | — |
| Cleaning, Health & Safety | Safe and hygienic work practices; cleaning of equipment | Stock management; health and safety awareness; grinder and machine cleaning and maintenance | — |
| Water Quality | Impact on brew quality and machine function | SCA water test and guidelines | Measuring TDS, alkalinity, total hardness and pH; water filtration testing and systems |
| Customer Service & Café Management | The customer experience | Customer interactions, and cost and goods | — |
| Simple Financial Concepts | — | — | Cost and goods |
Read that table as a study checklist. Anything not on it is not on the paper — which is why manual pour-over devices, cupping-form scoring, and green-grading defect counts, useful as they are, are not where Barista Skills marks live.
What the Papers Actually Test
Three question shapes dominate:
- Number recall. "What is the target steaming temperature?" "What is the ideal extraction yield?" These are free marks if you have memorised the figures and lost marks if you have not.
- Cause and effect. "A shot runs in 18 seconds — what do you adjust?" "Milk steamed to 75°C tastes how?" You must connect a symptom to a single correct correction.
- Definition discrimination. "Which statement distinguishes total hardness from total alkalinity?" Two options will be superficially plausible; only one is technically correct.
Exam Technique
- Budget by the clock, not by the question. One minute each. If a question needs more, flag it and return — an unanswered question and a wrong one score the same.
- Answer what is asked. A question about alkalinity is not answered by a fact about hardness, however true.
- Watch for level cues. Professional questions often specify a mechanism ("which protein", "which acid"); Foundation questions rarely do.
- Do not over-think the distractors. These are competency exams, not puzzles. The straightforwardly correct answer is usually correct.
- Sit the exam close to the course. Theory papers are typically completed online within a window after class (commonly around 20 days, set by the trainer). The recall curve is steep — book it early, not on the last day.
Trap: revising from generic barista content found online is the most common preparation failure. Match your revision to the subject-area table above, and prioritise the numbers: 9 bar, 92–94°C, 25–30 s, 1:2, 18–22% extraction yield, 1.15–1.45% TDS, 60–65°C milk, 55 g/L Golden Cup ratio.
