This study proposes a novel methodology for identifying top-performing researchers based on a composite performance index (CPI). Unlike existing rankings, this framework presents a multidimensional approach by integrating sixteen weighted bibliometrics metrics, spanning research productivity, citation, publications in top journal percentiles, authorship roles, and international collaboration, into a single CPI, enabling a more nuanced and equitable evaluation of researcher performance. Data were retrieved from SciVal for 1996\u20132025. Two ranking exercises were conducted with Kazakhstan as the analytical unit. Subject-specific rankings identified the top 1% authors within different research areas, while subject-independent rankings highlighted the overall top 1%. CPI distributions varied markedly across disciplines. A comparative analysis with the Stanford\/Elsevier global top 2% list was conducted as additional benchmarking. The results highlight that academic excellence depends on a broad spectrum of strengths beyond just productivity, particularly in competitive disciplines. The CPI provides a consistent and adaptable tool for assessing and recognizing research performance; however, future refinements should enhance data coverage, improve representation of early-career researchers, and integrate qualitative aspects.<\/jats:p>","DOI":"10.3390\/publications13040055","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T17:32:01Z","timestamp":1762191121000},"page":"55","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Novel Methodology for Identifying the Top 1% Scientists Using a Composite Performance Index"],"prefix":"10.3390","volume":"13","author":[{"given":"Alexey","family":"Remizov","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, School of Engineering and Digital Sciences, Nazarbayev University, Astana 010000, Kazakhstan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6625-8811","authenticated-orcid":false,"given":"Shazim Ali","family":"Memon","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, School of Engineering and Digital Sciences, Nazarbayev University, Astana 010000, Kazakhstan"}]},{"given":"Saule","family":"Sadykova","sequence":"additional","affiliation":[{"name":"Office of Research Policy and Analysis, Nazarbayev University, Astana 010000, Kazakhstan"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1204","DOI":"10.1016\/S0140-6736(20)30925-9","article-title":"Global burden of 369 diseases and injuries in 204 countries and territories, 1990\u20132019: A systematic analysis for the global burden of disease study 2019","volume":"396","author":"Abbafati","year":"2020","journal-title":"The Lancet"},{"key":"ref_2","first-page":"e141832.26907","article-title":"The rising trend in authorship","volume":"2","author":"Aboukhalil","year":"2014","journal-title":"The Winnower"},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Agarwal, A., Durairajanayagam, D., Tatagari, S., Esteves, S.
