What is 1KA?


The 1KA application is an open-source application that provides support for online surveys. It is an online service (SaaS - Software as a Service) that combines support for three key components:

  • Development, design and technical creation of an online questionnaire
  • The implementation of online survey: support for invitations, publication and distribution of data
  • Compiling and analysing data and paradata

Basic guideline of 1KA is to minimize the number of clicks - hence the designation of OneClickSurvey (EnKlikAnketa). All operations are therefore carried out with a minimum number of clicks or pressures on the keyboard (keystrokes). 

1KA as the application can be installed on any sufficiently powerful server. Parent installation of the 1KA application is on the www.1ka.si domain on the server of the Centre for Social Informatics, Faculty of Social Sciences, University of Ljubljana where it is possible to use the corresponding 1KA service for online surveys free of charge, under certain general terms of use. Of course, the 'free of charge' use does not apply to the specific needs of users who would request some additional work (e.g. introduction into 1KA, training, preparation of questionnaire, data analysis, assistance with installation etc.). In case of specific needs - based on prior agreement - additional services are charged by non-profit prices

The 1KA service for online surveys hosted over a 1.5 million completed questionnaires on just the parent installation (www.1ka.si) in 2015 alone. The total number of registered users in 2017 exceeded 45,000.

A local installation on the user's computer is not necessary. It is, however, be performed locally - in terms of installation of 1KA application on a desktop computer, laptop or tablet (Windows) - i.e. as an off-line 1KA application for the purposes of personal interviewing using a computer (CAPI - Computer Assisted Personal Interviewing).
