ISO 11132:2012给出了监控和评估定量描述小组整体绩效以及每个成员绩效的指南。评估员小组可以用作评估感官属性大小的工具。绩效是衡量专家组或评估员对被评估产品进行有效属性评估的能力。它可以在给定的时间点进行监控，也可以随时间进行跟踪。绩效包括小组检测、识别和测量属性的能力，以与其他小组或评估员类似的方式使用属性，区分刺激，正确使用量表，重复自己的结果，以及重现其他小组或评估员的结果。规定的方法允许监测和评估小组和评估人员的一致性、可重复性、无偏见和辨别能力。还包括对专家组成员之间协议的监测和评估。监测和评估可以在一次会议或一段时间内进行。通过监控绩效数据，小组组长可以提高小组和评估员的绩效，确定问题和再培训需求，或者确定表现不好的评估员是否能够继续参与。ISO 11132:2012中规定的方法可供专家组组长用于持续评估专家组或独立评估员的绩效。ISO 11132:2012适用于培训中的个人或小组以及已建立的小组。
ISO 11132:2012 gives guidelines for monitoring and assessing the overall performance of a quantitative descriptive panel and the performance of each member.A panel of assessors can be used as an instrument to assess the magnitude of sensory attributes.Performance is the measure of the ability of a panel or an assessor to make valid attribute assessments across the products being evaluated. It can be monitored at a given time point or tracked over time. Performance comprises the ability of a panel to detect, identify, and measure an attribute, use attributes in a similar way to other panels or assessors, discriminate between stimuli, use a scale properly, repeat their own results, and reproduce results from other panels or assessors.The methods specified allow the consistency, repeatability, freedom from bias and ability to discriminate of panels and assessors to be monitored and assessed. Monitoring and assessment of agreement between panel members is also covered. Monitoring and assessment can be carried out in one session or over time.Monitoring performance data enables the panel leader to improve panel and assessor performance, to identify issues and retraining needs or to identify assessors who are not performing well enough to continue participating.The methods specified in ISO 11132:2012 can be used by the panel leader to appraise continuously the performance of panels or individual assessors.ISO 11132:2012 applies to individuals or panels in training as well as for established panels.
