The opinions here presented were gathered from 104 in-depth interviews, 192 surveys and the close relationship with five families. Individual opinions have been elicited in a gradual fashion by asking for overall opinion regarding the government’s language policies before entering the subject of school choice throughout the survey and interviews. The in-depth interviews were usually one or two hours in length. These interviews began asking details of a person’s life, language usage and education, and then sought to gather the individual perspective on the development of language education, language policy at large and local schools, and concluded with a mapping of terminology of difference. The surveys dealt with the same issues but in more limited fashion (a Multiple Choice, rather than a Discussion Question). The interviews were conducted in places chosen by the person being interviewed after stressing the personal and perhaps sensitive nature of some of the questions and answers. The surveys, on the other hand, were mostly conducted in schools and wherever volunteers were found: in parks, bars, cultural events and associations. Where the interviews covered mostly adults (non-high school students), the survey mostly represents the school attending population between 16-21. Out of 104 interviews, 90 were adults over the age of 21, inversely, from 192 surveys, 136 were students.
Questions such as "why ikastolas became public or private" and "why some public schools closed" are often tied to explanations of political motives. The question, Have changes in language education policy been driven by political interests? is often answered without ever having been asked.
