Testing Academy
Certification, employment and a community that endured.
Across two decades of operation, Testing Academy is estimated to have trained between 1,800 and 2,200 delegates.
Delegates progress to ISTQB certification, and many move into software testing and quality roles. The relationship does not end with the course: alumni remain connected through active WhatsApp communities, peer support and periodic meet-ups, creating a professional family that continues to help people enter and grow within the field.
This is an informed institutional estimate based on two decades of Academy operations. The range reflects incomplete historical registers and will be refined as those records are consolidated.
