Ghana has made a decision about science, and the furniture implications are only now arriving. Under an initiative called “Operation Double Science Enrolment”, led by the Free Senior High School Secretariat, the Ministry of Education set out to lift senior high school science enrolment to at least 25 per cent, against 12 per cent at the time. The longer-term goal, from the Education Strategic Plan covering 2018 to 2030, is a 60/40 science and STEM-to-arts split. To make room for it, the Ministry reported launching several initiatives including “the construction of 300 new laboratories and the renovation of existing laboratories in selected SHSs nationwide,” alongside virtual laboratories introduced by CENDLOS. The World Bank’s own completion note on the sector frames the same agenda—”Ghana is seeking to strengthen Science, Technology, Engineering and Mathematics (STEM) and technical education as part of its broader effort to build human capital, improve productivity, and respond to growing labor market demand for technical and digital skills.” Three hundred new rooms are being built. This guide is about school science laboratory furniture in Ghana—and specifically about the ratio the benches must satisfy when the enrolment target lands.
What Kind of Laboratory Ghana Is Actually Building
Ghana’s approach has a distinctive shape, and it changes the furniture brief:
- Virtual laboratories arrived first, in some schools. CENDLOS introduced them so that schools could “conduct laboratory practicals without physical laboratory equipment.” Virtual labs solve demonstration; they do not solve the titration bench, the microscope station or the fume cupboard. The physical bench is still required for the practicals that are assessed.
- Capacity was expanded, deliberately and at scale. Three hundred new laboratories plus renovations is a capital programme, not a pilot.
- Teacher and technician capability was treated as part of the same programme, which means schools are expected to run these labs at volume—and a lab that runs at volume consumes bench positions weekly, not occasionally.
Put together, the question for any single school is no longer “do we have a laboratory?” It is: does the laboratory fit the science cohort it is about to receive?

Specification Benchmarks
Treat these as design targets to confirm with your supplier, not as regulator-published dimensions:
| Feature | Design target | Why It Matters |
|---|---|---|
| Bench length per student | 600–750 mm (700 mm target) | Two students sharing less than 1.4 m cannot both manipulate apparatus safely |
| Bench height | 850–900 mm | Standing work at SHS level; stools then sit below the bench edge |
| Reagent shelf | Above bench, with a raised lip | Without a lip, spills run down onto the working surface |
| Bench top material | Epoxy resin or high-pressure laminate | Coastal humidity swells raw board and acid attacks it |
| Sink | Acid-resistant, deep trap, 1 per 2–3 benches | Shared across too many benches and the queue replaces supervision |
| Fume extraction | Chemistry positions only, ducted or filtered | Localised extraction is cheaper than rebuilding a wall later |
| Services | Water, drain, power and gas routed in the bench | Exposed surface runs are the first thing that gets damaged |
| Power | 13 A sockets per bench position | Microscopes, hotplates and meters |
| Stools | Height-matched to bench, non-tip base | Mismatched stool height is the commonest safety complaint |
| Glassware storage | Closed, lockable, off the floor | Harmattan dust and breakage both end in a closed cabinet |
| Frame finish | Powder-coated, stainless fixings | Coastal salt air attacks fasteners before it attacks the frame |
Purchase priority: services (water, drain, power, extraction) first, bench length per student second, bench-top material third, fume extraction fourth, stools fifth.
The Practical-Session Arithmetic
A laboratory bench is not a desk. It is a throughput device, and its required size is set by the timetable, not by the roll.
Worked example, using clearly labelled planning assumptions for a 900-learner senior high school with one practical per science subject per week, three sciences, roughly 30 students per supervised session, and one laboratory available for about 30 usable sessions a week:
- Science cohort at the strategic target (60% of 900): 540 students.
- Weekly student-practical attendances: $540 \times 3$ subjects $=$ 1,620.
- Sessions required: $1{,}620 \div 30$ students per session $=$ 54 sessions per week.
- Laboratories required: $54 \div 30$ usable sessions $=$ 1.8 → two laboratories.
- Bench positions: at 30 students per session across two labs, you need 60 positions—30 per laboratory.
- Bench length: at two positions per bench at 700 mm each, a bench is 1.4 m long, so 30 benches per laboratory means 42 linear metres of bench per lab.
- Now run it at today’s 12 per cent: 108 science students × 3 $=$ 324 attendances $\div$ 30 $=$ 11 sessions $\div$ 30 $=$ 0.36 of a laboratory. One modest lab looks adequate.
- Now run it at the 25 per cent interim target: 225 science students × 3 $=$ 675 attendances $\div$ 30 $=$ 22.5 sessions $\div$ 30 $=$ 0.75 of a laboratory—a single lab running at three-quarters of capacity, with no headroom for setting up between subjects, breakdowns or examination periods.
The rule to take away: a single laboratory satisfies Ghana’s 12 per cent present and fails its 25 per cent interim target. Size the room and its services for the 60/40 destination, and you never have to close a working laboratory to rebuild it.
Build the Services for the Target, Buy the Benches in Phases
There is an asymmetry here that decides how to phase the money:
- Services are irreversible. Water supply, drainage falls, extraction ducting and power circuits are set when the room is built. Retro-fitting a fume extraction run through a finished laboratory means closing it, and a closed laboratory is a cohort of students with no practical that term.
- Benches are modular. A bench is a unit you can add. Two labs’ worth of service points installed now, with one lab’s worth of benches bought now, costs far less than two rounds of construction.
So the phasing rule is: install the service infrastructure for the 60/40 science cohort, and buy benches in the ratio you can staff today. Then add benches as enrolment rises—the water, drain and power are already there.
Two further points that carry real money:
- Buy the stool with the bench. A bench bought separately from its stool ends up with a mismatched height, and a mismatched stool is both a safety complaint and a replacement cost.
- Price the sink per bench-cluster, not per room. A single sink serving too many benches turns a practical into a queue, and a queue replaces supervision with waiting.
Ghana-Specific Constraints
- Coastal humidity (Accra, Tema, Takoradi, Cape Coast): Salt-laden air attacks steel fasteners before it attacks the frame, and humidity swells raw board. Specify powder-coated frames, stainless fixings and epoxy or high-pressure laminate bench tops.
- Termite pressure: Ghana’s termite load makes board-based bench carcasses a false economy. Steel frames with sealed edges are the durable answer, and the general principles are covered in our anti-mildew analysis (Internal Link).
- Harmattan dust (December to February): Fine dust settles into open storage and contaminates optics and glassware. Specify closed, lockable storage for instruments and glassware.
- Intermittent water supply: Where supply is not continuous, the laboratory needs on-site reserve storage and a drain that works regardless—a practical that stops mid-way for want of water is a lost session.
- Intermittent power: Provide for uninterrupted microscope and meter use, and prefer electrical heating over bottled gas where a school cannot guarantee safe cylinder handling and leak checks.
- Two chemistry realities: Acid and alkali resistance must be specified for the bench top itself, and reagent shelving above a working surface must carry a lip so a spill cannot run down onto a student.
Procurement Channels and Price Benchmarks
- Ministry of Education and the Ghana Education Service: GES’s own figures put the system at 16 regions, 261 districts, 40,000+ schools and 9M+ students, and it publishes its mandate and resources centrally. Policy and national standards sit here.
- The Free SHS Secretariat: The body that led “Operation Double Science Enrolment” and therefore the programme most directly responsible for science capacity demand.
- CENDLOS: The Centre for National Distance Learning and Open Schooling, which introduced virtual laboratories into second-cycle schools—and which therefore shapes what the physical lab is used for.
- The Ghana Accountability for Learning Outcomes Project (P165557): The World Bank-supported project under which the STEM completion note sits, relevant for schools inside donor-funded programmes.
- District, municipal and metropolitan assemblies: The channel for locally funded school infrastructure.
- Private and faith-based senior high schools: The fastest adopters of engineered steel laboratory furniture and the easiest to serve at short notice.

Supplier Vetting Checklist
- Give the supplier your target science ratio, not your current one, and ask them to return the laboratory count and bench-length calculation.
- Confirm bench length per student at 700 mm, measured from the drawing—not a nominal “standard bench.”
- Ask what the bench top is made of and how it resists acid, in writing.
- Check that reagent shelving carries a lip, since this is the detail most often omitted.
- Require a sink-to-bench ratio, and refuse a room-level answer.
- Verify fixings are stainless, not merely plated—coastal salt air finds plated fasteners first.
- Confirm the extraction route and who installs the ducting, before benches are ordered.
- Visit a school running practicals weekly and watch one full session, including the clear-down between subjects.
Conclusion
Ghana has already committed: 300 new laboratories, renovated existing ones, virtual laboratories from CENDLOS, and a strategic destination of a 60/40 science and STEM-to-arts split. The arithmetic says a 900-learner school needs two laboratories and roughly 42 linear metres of bench per lab at that destination—while one modest lab satisfies today’s 12 per cent and fails the 25 per cent interim target. So build the water, drainage, power and extraction for the destination, buy the benches in the ratio you can staff now, and keep the stools matched to the benches. That way the enrolment target arrives as a purchasing decision rather than a construction project.
