A Research On Applied Pattern And The Rater Of Leaderless Group Discussion

Leaderless Group Discussion (LGD) is a Situation Simulation test technology of Assessment Center, and is an effective personnel test. In the simulation team, the candidates discuss a problem or a situation, and the raters evaluate their abilities by watching their behaviors to find which one is competent for a position. LGD is used for the selection and diagnosis of the managers.Some research findings suggest LGD has good reliability and accepted availability. Many organizations have used it widely in practice. But there is still no systematic LGD applied pattern. In our research, the first part is about the applied pattern of LGD. It suggests the applied pattern of LGD includes five phases: test tools selecting, LGD materials preparing, execution preparing, executing and summarizing. The second part is about the reliability and availability of LGD. Its results suggest: the reliability is good in total and inconsistent on some dimensionalities. There are not only significant consistent of raters but also significant inconsistent in seven groups. It has been proved that LGD has accepted availability on some dimensionalities. And the third part is about the research of the raters. It suggest: the consistent of raters is very good in total and in each dimensionality. The consistent of different raters is very good in total, but not good on certain dimensionalities. The different raters have significant different levels of rating. The Vocational Value of the valuator maybe works on their evaluation of LGD.
