With globalization, changing international economic conditions, especially with the advent of the knowledge economy, and the importance of lifelong learning, the nature and functions of knowledge are gradually changing. This has created changing requirements for 21st century learners' skill sets, such as the ability to think critically and creatively, the ability to learn independently and collaboratively, the ability to learn formally and informally, as well as the ability to both compete and collaborate, etc. The 21st century is a century of very rapid and continuous development around the world, which has a very dynamic and cyclical impact on societies around the world. Development leads to production, and production leads to further development. For this reason, the importance and influence of the ability to "think differently" is gradually increasing in all societies. Critical thinking plays an important role in this process. The purpose of this trial experimental study was to evaluate and determine the critical thinking skills of future educational psychologists. The testing study was conducted with the participation of 90 students at the faculties of pedagogy and psychology of 2 Kazakhstani and Lithuanian universities. The starting point in assessing the critical thinking of the studied students was testing using the self-translated questionnaire "Critical Thinking Skills of Prospective Teachers" (Kavenuke et al., 2020) before and after the experimental phase of the study. The questionnaire contains 9 statements evaluated on a seven-point Likert scale.
