A comprehensive understanding of the basic concepts of statistics is needed to convey the material in class. The results of the discussion with the Mathematics MGMP of Kediri City, a workshop is needed to deepen the understanding of mathematics teachers, especially in the material of normal distribution and binomial distribution. In addition, Material about item analysis and standard setting is need to be introduced. Both materials can be used in evaluating learning. The workshop was held in two days. The first workshop held on 4 November 2020.  Material for this day was normal distribution. At the end of the activity on this date, participants were given practice questions that should to be uploaded on google classroom. Second workshop held on 17 November 2020.
