Diagonal English needed a user-friendly school management system that would allow it to:

At a glance

  • Goal: Centralize operations for a fully-online school and reduce admin friction
  • Key wins: Better teacher handovers, faster communication, improved attendance tracking and billing accuracy
  • Used features: Dashboards, Scheduling, Attendance, Notes, Student profiles

Read on to learn how Teach ’n Go helped Diagonal English streamline communication, manage data more efficiently, and save hours of time.

The School

Through private and group classes, Diagonal English offers a variety of online courses to help adults improve their English communication skills.

The school has over 10 years of experience helping adults improve English for job interviews and professional settings.

Diagonal English provides preparation classes for Cambridge B2 First and C1 Advanced examinations.

Since 2012, Diagonal English has worked with over 200 companies and 6,670 students—and helped 2,085 people become FCE and CAE certified.

The Challenge

Diagonal English relied on a generic school management app and Google Sheets to manage day-to-day processes.

The app was complex, and teachers and administrators didn’t receive training on how to use it effectively.

As the school grew, it became increasingly time-consuming to track data across multiple folders.

Google Sheets were prone to mistakes and, on rare occasions, were accidentally deleted.

Neither system provided clear oversight or a reliable way to centralize information across the business.

The Solution

In 2020, Diagonal English realized it needed a platform that could keep up with the demands of online learning.

The new system had to be user-friendly and help the team manage operations from one central place.

After market research, Diagonal English chose Teach ’n Go.

Teach ’n Go helped the team reduce human error, become more efficient, and improve internal communication.

Shortly after we started offering online classes due to the pandemic, we realized that the systems we had in place weren't the right fit. We needed something that would help our staff manage lessons and attendance, as well as support our students' learning. I managed to use Teach ’n Go within a few days and we were excited to see it would allow us to centralize all of our data, instead of having it stored across Google Drive.

The Results

Everybody’s on the same page

Diagonal English uses Teach ’n Go to track classes, schedules, and daily operations in one place.

This is especially valuable because teachers work on a rotational schedule.

With real-time dashboards, administrators and students can easily see which teacher is taking each lesson.

Teachers also leave detailed class notes for each other—helping smooth handovers and improve continuity.

  • Stay up-to-date with the lessons they’ve delivered
  • Know where to pick up with the class next time

Teachers review notes before class to understand absences and lesson make-ups within the group.

They also upload videos and class materials to Teach ’n Go so students can access coursework anytime, anywhere.

Streamlined communication

Teach ’n Go notes have streamlined communication between teachers and administrators.

Instead of endless emails and messages, updates live with the class—ready to reference whenever needed.

When I want to send emails out to our students, all I need to do is choose their contact details from their profiles in Teach ’n Go. This is much quicker than trying to find multiple email addresses to copy and paste into Outlook. Teach ’n Go has saved us a lot of time because all of the information is in the system for us to access.

Improved attendance management and billing

Some Diagonal English teachers work on a freelance basis, so tracking delivered lessons is essential for accurate payroll.

With Teach ’n Go calendars and attendance, administrators log hours and record cancellations with ease.

This reduces human error and helps ensure teachers are paid accurately for the lessons they deliver.

Looking Ahead

Next, Diagonal English plans to use Teach ’n Go to generate attendance reports for students’ course sponsors.

This will give funders clearer oversight into attendance and improve accountability.

With great outcomes already, Diagonal English is excited to continue using Teach ’n Go to support teachers and students.

Compared to the previous system we were using, Teach ’n Go is very user-friendly and helps us manage our school more efficiently on a daily basis. I can’t wait to use more features to continue streamlining our processes and save even more time.
