Everything here is commissioned by organisations rather than by individuals: assessment companies, test publishers, ministries and agencies, employers, clinics and research groups. The subject is the instrument, or the inference somebody has drawn from it, rather than any one person’s result. Fees depend on scope and are quoted per engagement. The first conversation costs nothing and is usually short, because a fair share of enquiries turn out not to be measurement questions at all, and it is quicker for everyone to say so.
Specialist services
Expert witness
Independent opinion and testimony on test validity, adverse impact, measurement invariance and algorithmic fairness in selection.
Scientific advisory
A standing advisor for assessment companies whose validity claims must survive procurement, diligence and the EU AI Act.
Assessment data analysis
National deep dives on PISA, PIAAC, TIMSS, PIRLS and ICCS data, including the comparability audit that says which findings will hold.
Publisher partnership
Regional adaptation, invariance testing and norming for test publishers entering Montenegrin, Serbian, Croatian and Bosnian markets.
Working languages and reach
Work is delivered in English and in Montenegrin, Serbian, Croatian and Bosnian. Assessment and partnership work is concentrated in Montenegro and the wider region. Expert witness, advisory and data analysis work is taken internationally.
