Faster and still good
Lessons made quickly were judged no worse than lessons that took longer.

What changed
in the classroom.
National pedagogical inspectors tested the lessons. The Inspectorate General of Education reported on the classrooms. Here is what they found, in their own numbers.
Teacher time
From hours of preparation to minutes
Before, seven in ten inspectors spent more than an hour preparing a single lesson. With NDX, they judged the lessons faster, useful and ready to teach.
Faster
96.1%
Said preparing a lesson was faster than their usual practice. 89.6% said much faster.
- 0196.1%Useful
Rated the lessons useful or very useful: 100% in French, 93.3% in English.
- 0258.4%Ready to teach
Needed no edits or only minor ones. 32.5% needed none at all.
- 0383.1%Would use it again
Firm intent to keep using it. Not one said no.
- 0435.1%Under five minutes
Of lessons were generated in less than five minutes.
- 0570.4%The starting point
Spent more than an hour preparing one lesson before.
What inspectors found
Speed did not cost quality
The inspectors' own analysis, across both language systems and every pathway.
Editing is the real cost
What lowered usefulness was rework, so the work goes into lessons that need less of it.
Both systems, every pathway
Anglophone and Francophone, general, technical and teacher training, in more than 25 subjects.
National infrastructure
Inspectors came to see it as instructional infrastructure for the country, not a classroom gadget.
In their words
What inspectors said
“I was excited having all lessons generated and tracked in a click.”
“The most useful was the homework and assessments.”
“The hook relating to Bamenda made the lesson inclusive.”
“The student-centred approach of the lesson and the hands-on exercises.”

Early signs in results
Equipped schools held up better
In a year when the national DECC pass rate fell from 70.2% to 63.2%, equipped schools did better than their peers. The Inspectorate calls these first, encouraging indications, not proof of cause.
Far North pass rate
−2.2
Equipped schools
−4.5
Other public schools
Change in DECC pass rate, in points, in the region where the fall was hardest.
Schools starting below 40%
61.3%
Equipped schools
52.6%
Other public schools
Share of schools that raised their pass rate.
Schools starting at 40–60%
44.4%
Equipped schools
30.0%
Other public schools
Share of schools that raised their pass rate.
On the GCE honour roll: 56% of the laureates from public schools came from equipped schools.
In the classroom
When the lesson is ready in minutes, the teacher’s time goes back to the pupils.
What holds schools back
Power, people and connection. Not the technology.
Only one school in six reported a technical problem. The barriers are the conditions around the classroom, which is what NDX is built for.
Barriers schools reported
- Electricity66.7%
- Teacher hesitancy61.9%
- Connectivity59.3%
- Technical problems16.5%
No grid, no stop
Solar power and battery storage keep the classroom running when the grid does not.
No internet, no stop
The classroom AI runs on the classroom's own hardware, online or offline.
Confidence first
Master trainers in every school, certification the ministry owns, and coaching after go-live.
