This article describes research into the causes of failures of students in solving tasks with parameters. As a research tool, a non-standardized test was used, which was fulfilled by 124 respondents at the age of 18. Following analysis of the works of the respondents revealed basic misconceptions of the term parameter. Another reason, which was revealed by research, is formal setting of the conditions to solve the tasks. On one side the shortage is linked to the way students learn Mathematics. It is largely preferred learning of the whole task procedures to understanding the particular steps. On the other hand, it is related to the lack of definition of the terms parameter and the unknown. At the same time the misconception is unveiled, consisting in considering the term "-a" for always negative. The article, along with a description of the research and analysis of the test results, offers the basic solutions of discovered reasons of why students’ fail to solve the tasks with parameters.
