A strong employment message markedly increased program effects (this was the strongest effect).
Emphasis on personal client attention increased program effects.
Large caseloads reduced program effects.
Reliance on basic education reduced program effects in the short run.
High unemployment reduced program effects.
Program effects did not vary consistently with client characteristics.

Others agreed, suggesting that if some modest core measures for critical outcomes and variables could be established for common use, it would greatly facilitate the work of meta-analysis.
