高低分分段双向截除法高低分分段双向截除法即在考核打分时为消除考核者主观打人情分的影响，而对考核得出的结果按所有考核成员得出分值的平均值的一定比例限定高低分区间，对超过此区间的考核分数的使用进行限定，在统计成绩时而不予考虑、计算。此种方法可控制打分者在一定程度上约束自己的打分行为，将其控制在一定程度内，否则其打出的分数将视为无效，实际上也即相当于放弃了自己的投票权。由于实际考核工作中，评委主观打分和打人情分的倾向较普遍，因而对于优化考核有一定意义。但此种方法对考核者人数较多的情况下更适用，而考核者人数较少时（更易受事前操纵、考核者信息泄露风险系数增加、恶意评分者博弈动机增强等因素影响），其有效性将会降低。
