The verdict in three sentences
The school-parent relationship rides on lost correspondence books and unread messages: an app with SMS notifications reaches a read rate around 90 %. Grades, absences and events land directly on the parent's phone, for an SMS cost of 15 to 25 FCFA each. The result: 30 % fewer unnecessary meetings and parent engagement up around 45 %.
SMS, still the king channel
SMS depends on neither a smartphone nor a data connection, making it the most reliable channel to reach every parent. WhatsApp complements it for rich content.
| Channel | Read rate | Unit cost | Prerequisite |
|---|---|---|---|
| SMS | ~90 % | 15 to 25 FCFA | None (any phone) |
| ~70 % | Low (data) | Smartphone + data | |
| ~25 % | Near zero | Address + habit | |
| Paper notebook | Variable | Paper | Manual delivery |
What the app notifies
Every school event becomes a traceable notification, with a history viewable by both parent and school.
| Event | Channel | Delay |
|---|---|---|
| Grade published | SMS + app | Immediate |
| Absence / lateness | SMS | Within the hour |
| Summons / meeting | SMS + WhatsApp | Scheduled |
| Event (trip, exam) | App + SMS | D-3 to D-1 |
| Payment reminder | SMS | Per schedule |
| Report card available | SMS + app | On issue |

Mrs Ndiaye manages student life at a 500-student school in Saint-Louis. She sends on average 6 SMS per student per month, i.e. 3,000 SMS at 20 FCFA, i.e. 60,000 FCFA/month. In return, unreported absences fall, meetings drop from 10 to 7 per term (-30 %), and parent engagement climbs about 45 %. The annual SMS cost (~720,000 FCFA) is absorbed by the administrative time saved.
