About the client

Classtime, Pollock Technologies Inc.’s flagship product, enables an educator to create questions on an internet-connected device (mobile phone, tablet, PC/notebook), push it to all student devices and track the performance of a class immediately in a class session. The teacher receives valuable information about the individual student’s performance and can intervene as deemed appropriate, thereby improving the overall learning progress of the class. By answering the questions, all students are fully engaged, which can also be analyzed after class and even over time to measure a single student or the entire classes development.

Classtime is trusted by more than 11,000 teachers globally.
