In order to solve the problem of employment skills assessment, a method using the Internet of Things training practice platform is proposed. The main content of this method is based on the research and analysis of the practical training platform of the Internet of Things. According to the data characteristics of the Internet of Things and through the construction of the practical platform, it is concluded that the development and construction of the practical training platform of the Internet of Things is highly feasible for the evaluation of employment skills. The experimental results show that the average RI value of data mining accuracy is 0.95, and the accuracy of data mining algorithm is high. Conclusion. It proves that the development and construction of the practical training platform of the Internet of things is feasible and accurate for the evaluation of employment skills.
