Burkina Faso CFPA/CAPA common mistakes
Burkina Faso CFPA/CAPA · Understand the traps and how to avoid them.
When calculating a seeding rate, the candidate divides the recommended dose per hectare by the plot area in square metres without converting units, or mixes grams and kilograms, and reports a figure that is off by a factor of 10 000.
Seeding-rate exercises are usually taught with a single worked example in hectares, and trainees memorise the formula rather than the unit chain. Under exam pressure they plug in the plot area in m² directly and never check whether the result is plausible for a 25 m² plot.
What to do instead
Before any calculation, write the full unit chain on the answer sheet (kg/ha → g/m² → g per plot) and cancel the units explicitly. Then apply a plausibility check: a 100 m² plot at 20 kg/ha must give about 200 g, so any answer in kilograms or in grams below 50 signals a conversion error. Practise with three plot sizes (10, 100, 2500 m²) until the chain is automatic.
The candidate describes a crop protection problem generically ('treat with a pesticide') instead of naming the pest or disease, the active ingredient family, the dose, and the pre-harvest interval.
Field training often stops at 'spray when you see damage', so trainees know the action but not the decision rules. Exam questions that present symptoms expect a diagnosis first, and candidates skip it because they are unsure of the identification.
What to do instead
Use a fixed four-line answer template for every protection question: (1) probable causal agent and the symptom that justifies it, (2) non-chemical measure first where possible (resistant variety, rotation, sanitation), (3) product family and dose per hectare of water, (4) pre-harvest interval and safety precaution. Build a personal table of the ten main local pests and diseases of sorghum, maize, cotton, tomato and cowpea, with these four lines for each.
In soil fertility questions the candidate recommends fertilizer without stating the soil constraint, the crop, the target yield, or the split application, and gives a single blanket dose.
Blanket recommendations circulate widely in villages ('two bags of NPK per hectare') and are easier to recall than a reasoned recommendation. Candidates do not realise that the marking scheme rewards the reasoning chain, not the number.
What to do instead
Answer in a fixed order: observed or measured constraint (pH, organic matter, previous crop), crop and target yield, nutrient balance, product and dose, timing and splitting, and one organic-matter measure. State explicitly why the second nitrogen split is placed at the crop stage you name.
The candidate lists vaccines or treatments for livestock without giving the route of administration, the age or weight of the animal, and the withdrawal period before milk or meat sale.
Trainees learn vaccine names by heart from campaign posters but rarely handle a syringe or read a notice. The withdrawal period in particular is skipped because it is not part of the memorised list.
What to do instead
For each of the main livestock diseases (Newcastle disease, pasteurellosis, anthrax, contagious bovine pleuropneumonia, internal parasites), write a card with: species and age, product and dose, route (ocular, subcutaneous, intramuscular, oral), storage condition, and withdrawal period for milk and meat. Rehearse giving the card aloud in under one minute.
In ration or feed questions the candidate mixes fresh fodder, hay and concentrate figures without converting everything to dry matter, and then compares the total with an animal requirement expressed in dry matter.
Feed tables are distributed in different bases (as fed, dry matter, crude protein percentage) and trainees copy numbers from whichever table is at hand. The dry-matter conversion step is the one most often omitted in class exercises.
What to do instead
Always start the answer with a small table with two columns, 'as fed' and 'dry matter', and convert every line before summing. Memorise the approximate dry-matter content of the three or four main local feeds (fresh grass, hay, cereal bran, cottonseed cake) so the conversion can be done mentally during the exam.
In farm accounting the candidate records a loan received as revenue, or omits family labour and own-seed from costs, so the calculated gross margin looks profitable when the holding is losing money.
Cash in hand is confused with profit, which is intuitive for anyone who has managed a small household budget. Family labour is unpaid in practice, so it disappears from the written calculation.
What to do instead
Apply three rules mechanically: loans and subsidies go to financing, not revenue; own inputs are valued at market price in costs; family labour is costed at the local daily wage and shown as a separate line. Close every exercise by producing both a cash-flow view and an economic view and stating which one answers the question asked.
The candidate describes how a machine works but cannot state the daily maintenance operations, the adjustment points, or the safety step to take before clearing a blockage.
Teaching is often demonstration-based with the trainer handling the tool, so trainees observe operation but never perform the pre-start checklist themselves. Exam questions on maintenance therefore get vague answers.
What to do instead
For each main item (knapsack sprayer, plough, seed drill, motor pump, thresher) write a numbered daily and periodic maintenance list and a 'before you touch it' safety line (engine off, pressure released, implement lowered). Practise the checklist physically on the centre's equipment until it can be written from memory.
On water and soil conservation the candidate recommends a structure (stone line, half-moon, zaï pit) without giving the spacing, the layout along the contour, or the catchment area it is designed for.
Structures are learned as names and pictures rather than as dimensioned techniques, and spacing rules are seen as details. The result is a correct name attached to an unbuildable design.
What to do instead
Learn each technique with its three numbers: spacing between structures, spacing within the line, and the slope range for which it is intended. Add the labour requirement per hectare and one maintenance operation per year. Answer format: problem, technique, dimensions, layout, maintenance.
In extension and community-organisation questions the candidate proposes a 'sensitisation meeting' as the whole answer, without identifying the target group, the channel, the message, or how the result will be measured.
Awareness meetings are the most visible extension activity in rural areas, so they come to mind first. Trainees have rarely been asked to design an intervention with indicators.
What to do instead
Structure every extension answer around five points: target group and its constraints, channel (farmer field school, radio, demonstration plot, lead farmer), content of the message, timing in the cropping calendar, and one or two verifiable indicators. Replace 'sensitise' with the specific behaviour that should change.
In mathematics and applied-science items the candidate writes only the final number, without the working, the formula, or the unit, and loses all method marks even when the figure is right.
School habits of producing a bare answer persist, and time pressure encourages skipping intermediate lines. Trainees do not know that the marking grid awards most points to the method.
What to do instead
Impose a personal layout on every numerical answer: data given, formula, substitution, intermediate result with unit, final result with unit and a one-line interpretation. Rehearse under timed conditions so the layout costs no extra minutes.
