On February, 18, The Higher School of Economics Center of Education Quality Monitoring held the seminar "Measurements in the Social Sciences". NTF experts made a presentation on "A systematic approach to the development of assessment tasks: from collecting evidence to analyzing the results"
Experts presented the approach to making the assessment - Evidence Centered Design, the general theoretical frame of this approach, the way how experts create the job bank, and the way how to assess the level of capacity of testees and difficulties of tasks.
Assessment of tasks and respondents is carried out using Bayesian network and at the seminar it was clearly demonstrated how the networks work and what mathematical foundations are laid in them. The whole explanation was built with examples of a real assessment that was being developed at the NTF - the ICL Test.
