Collecting data. We discussed entrepreneurship with our experts, studied the works of Asmolov, Osterwalder, and Blank, and gathered examples and anti-examples for case questions.
For example, it turned out that teenagers confuse the concepts of a problem, a problematic situation, and circumstances. We added the question about their differentiation to the tests.
Formulating questions. The cases mentioned by different experts were included in the pool of test questions. Then we changed the wording for schoolchildren: described the context, where the content allowed it, so that the question engaged them into the situation and its story.
Testing on the target audience. We gathered several groups of schoolchildren with various experiences in entrepreneurship and a group of adults to compare the data and make sure that the complexity of the questions is right.
Finally, we calculated the Test Standards, Reliability, and Discriminability.
