I'm currently putting together a screener to prepare for usability testing. This software will be used globally. I'd like to ask for the highest level of education and have the participants select from a list so that the analytics are cleaner than using an open text field.
The problem I foresee is that different levels of educational institutions do not map to each other across geographies.
The way I would as this question in the United States is:
What is the highest level of education you have completed?
- Some high school
- High school graduate
- Some college
- Trade/Technical/Vocational training
- Some postgraduate work
- Postgraduate degree
Is there a good way to generalize this question for a clearer, although inexact response?
