This is a significant step in designing and developing a learning program. At this stage, instructional designers check if all the scenario's planned activities, materials, program blocks, and modules are in the right places. Testing the program is not limited to looking through it quickly, it is a systematic check of the accuracy of the designed scenario and developed content, including the use of navigation and clarity for learners and trainers.

In virtual and hybrid learning, it is important to consider the UX/UI of the learning product's end-user. At this stage, it is useful to test the program and preview it as a trainer and as a learner. In Lanes Academy, we call it "to learn with the user's mouse in our hands!"
