Research on the effectiveness in improving salesforce performance through p
ersonnel selection procedures and training interventions was examined by me
ta-analytic techniques applied with 157 predictor-criterion effect sizes in
volving selection procedures and 12 effect sizes involving training interve
ntions. Significant effect sizes, on average, were obtained for (a) composi
te-domain assessment against both subjective (ratings) and objective (sales
performance) criteria, (b) single-domain assessment against both criterion
types, and (c) training interventions with respect to both criterion types
combined. Significant variability was found among individual effect sizes
within all categories of aggregation. Of the six specific categories of sin
gle-domain assessment considered, five yielded significant validity for eac
h of the two criterion types. Follow-up utility analyses revealed improveme
nts in sales productivity of from 14.8% to 34.1% for selection procedures a
nd of 23.1% for training. Associated dollar-based utility estimates indicat
ed particularly substantial dollar gains for organizations employing compos
ite-domain selection with rigorous selection ratios, and lesser, but still
substantial, gains from single-domain selection with rigorous selection rat
ios, and from training interventions. (C) 2001 John Wiley & Sons, Inc.
