For linguistic integration, our measure captures respondents’ assessment of their ability to read, speak, write, and understand the dominant language of their host country or region.
We use “can-do” statements to quickly measure native language proficiency. Can-do statements are self-assessments gauging what a person “can do” in a language, like read a newspaper or listen to and understand the radio. In the short form IPL-12 we ask respondent how well they can do the tasks described in two statements:
1. I can read and understand the main points in simple newspaper articles on familiar subjects.
2. In a conversation, I can speak about familiar topics and express personal opinions.
For the long form IPL-24, we add two additional statements:
3. I can write letters about my experiences, feelings, and about events.
4. I can listen to and understand the main points in radio or TV programs about familiar subjects.
