Computer-Assisted Measurement and Coding of Educational Qualifications in Surveys (CAMCES) 
===========================================================================================

**Short Description:** To overcome incompleteness in the case of long-list factual questions, a database query was incorporated in the survey procedure. To test different database interfaces, a split-ballot experiment was conducted using the example of educational attainment comparing a dynamic text field, a search tree and a long list.

**Experimental Details:** Random allocation of participants to three groups. Each group was shown self-report items on educational attainment in a different presentation form (dynamic text field, search tree or long list).
