On average, teachers spend 7 to 10 minutes per class taking attendance for 40 students using the traditional roll-call method. If a teacher conducts 6 classes per day, this results in over 1 hour per day spent on attendance alone, or nearly 200 hours per academic year. However, by switching to School Bright, this time can be reduced to just 1 minute with face recognition technology and automated data recording working in the background.
For schools across Thailand, administrators and teachers are facing the issue of “teaching time being consumed” by repetitive administrative tasks. Implementing School Bright’s cloud-based attendance system helps return valuable time to teachers, allowing them to focus on improving student learning outcomes while enhancing school management to meet digital standards.
How long does it take to take attendance for 40 students using traditional methods?
A closer look shows that roll call involves more than just calling names—it includes several time-consuming steps.
Breakdown of time spent on attendance
Calling names individually (4–6 minutes): Each student takes around 10–15 seconds on average
Waiting for responses (1 minute): Delays occur when students are distracted or do not hear their names
Recording attendance (2 minutes): Writing it down in a register or entering it into Excel afterward
➡️ In total, attendance takes 7–10 minutes per class, which equals losing 15–20% of teaching time daily.
Why is traditional attendance a major problem in schools?
The issue is not just about time, but also accuracy and data management.
Human Error: Teachers may mark the wrong student, or students may respond on behalf of others
Delayed information: Parents are not immediately informed whether their child attended class
Administrative burden: Teachers must later transfer data from paper into digital systems
Lost learning opportunities: Late lesson starts reduce classroom activity time

How does saving attendance time improve learning outcomes?

Continuous learning flow: Classes start immediately without interruption
More individual attention: Teachers can better support students who need help
Reduced teacher stress: Less administrative work leads to more energy for creative teaching
