Technologies is one of the subjects in general education that have been influenced by political, economic, technological, social and cultural developments. The teaching of this practical subject has been a historical component of the curriculum for many decades. This reflected the needs of society to provide the younger generation with the skills and knowledge necessary to ensure their smooth integration into the labour market. During specific periods, the content of the subject did not change significantly, despite historic disruptions in the economic, political and cultural context and these were reflected in the guidelines of Technologies programs. This has been demonstrated in the analysis of content of general education programmes and textbooks of Technologies in Lithuania. From the time the subject was introduced, pupils were taught practical skills for employment in industry, as well as to perform household work and promote traditional Handicraft. State institutions steered Lithuanian public education towards industryoriented, manual training and attempted to direct Lithuanian girls and boys into industrial production. However, the textbooks reflect the traditional view of what Lithuania’s people needed, namely basic knowledge of how to manage domestic life, and promote Handicraft and national traditions.

To create good and optimal school schedule is very important and practical task. Currently in Lithuania schools are using two programs for making the school schedule at the moment. But none of these programs is very effective. Optimization Department of Lithuanian Institute of Mathematics and Informatics (IMI) has created "School schedule optimization program". It has three optimization algorithms for making best school schedule. A user can choose not only few optimization options and get few optimal schedules, but some subjective and objectives parameters. The making of initial data file is advanced in this program. XML format is used for creating initial data file and getting all optimal results files. The purpose of this study is to analyze used optimization algorithms used in "School schedule optimization program" and to compare results with two most popular commercial school scheduling programs in Lithuania.
