This study determined and recommended empirically-based criteria for performing person matching as a psychometric scoring methodology to predict specialty selection for a profession.This study compared the predictive hit rates of standard scoring and three calculations of person matching based upon ex post facto data collected on 5,143 medical students who had taken an interest inventory and had entered their medical residency.The results suggested the following conclusions to the five hypotheses.First, the inclusion of all 150 raw item scores when person matching produced more accurate hit rates than when using the 18 scale scores.Person matching on the item level appears to be more accurate than person matching on the factor or scale level.Second, using the top 20 person matches produced the highest hit rates as compared to the top match and top 5 and 10 singular matches.Third, standard scoring outperformed person matching for the top match.However, the 150 items and the 30 items were able to outperform standard scoring when looking beyond the top match to offer medical students several medical specialties to research for further consideration.Fourth, gender differences were less pronounced for person matching than standard scoring.Fifth, the predictive hit rates were slightly higher when combining standard scoring and person matching psychometric scoring methodologies to person match based upon only 30 items on the inventory.In conclusion, person matching is worthy of Counseling and Human Development Services considerable research attention in interest inventories as the benefits to women and a quickly-changing, global workforce could be immense.provided to me by my advisor Dr. Mark Savickas.His enduring encouragement was the catalyst for pursing a Ph.D. and becoming a counselor educator.Thank you for your constant support and guidance to persevere with both occupational and personal challenges, which has allowed me to find the field that I love.I would like to thank Dr.
