This study is relevant given the growing reliance of post-Soviet higher education systems on bibliometric indicators to evaluate academic performance and allocate research funding. The purpose of the study is to examine whether generational cohorts of productive scientists in Kazakhstan differ in their publication patterns under the transition to bibliometric-based research evaluation. The study is based on a bibliometric analysis of 220 highly productive authors across 22 subject areas using Scopus and SciVal data for 2018–2023, with correlation analysis applied across three age cohorts (under 40, 41-55, and 56+). The results reveal significant generational differences in publication strategies. Among researchers under 40, a very strong correlation is observed between total publications and Q1 journal output (r = 0.95), and between publication activity and international collaboration (r = 0.98). This cohort also demonstrates higher publication activity in internationally co-authored papers and stronger alignment with formal bibliometric indicators. In contrast, the 41-55 cohort shows the weakest relationship between publication output and Q1 publications (r = 0.40), lower levels of leading authorship, and less pronounced integration into international publication networks. Researchers aged 56+ occupy an intermediate position but demonstrate the highest share of publications in journals later excluded from Scopus, indicating greater exposure to potentially problematic publication practices during earlier stages of Kazakhstan’s research system transformation. The findings suggest that highly productive scientists from different generational cohorts respond differently to formal bibliometric evaluation requirements. The presence of publications in journals later excluded from Scopus across all cohorts suggests that bibliometric-based evaluation systems may encourage strategic responses to performance criteria.
