Productivity Index

productivity_score = pubs_per_year * 10 + cites_per_year * 0.5 + grants_active * 15

Publications per Year

pubs_per_yr = pubs_per_year

Citations per Year

cites_per_yr = cites_per_year

Citations per Publication

avg_cites_per_pub = cites_per_pub

How It Works

Research Productivity Index

This composite index combines three dimensions of research output into a single score for self-assessment and goal setting.

Formula

Index = (Pubs/Year x 10) + (Citations/Year x 0.5) + (Active Grants x 15)

The weights approximate relative effort: publications represent direct output, citations indicate reach, and grants reflect funding competitiveness.

This is a self-benchmarking tool. Compare your score across years to track growth, not across fields where norms differ.

Worked Example

Over 3 years: 8 publications, 120 citations, 2 active grants.

publications = 8citations = 120grants_active = 2years_in_period = 3
  1. 01Pubs per year: 8 / 3 = 2.67
  2. 02Citations per year: 120 / 3 = 40.0
  3. 03Index = 2.67 x 10 + 40.0 x 0.5 + 2 x 15 = 26.7 + 20.0 + 30.0 = 76.7
  4. 04Citations per publication: 120 / 8 = 15.0
