The current project – “Evaluation – An Opportunity to Improve Students’s Educational Results” has been developed in accordance with the development strategy of “St. Paisii Hilendarski” High School. A key priority for the school is achieving high efficacy in the educational process, an indicator for which is the difference between the mean results of students and the highest and lowest marks. In this respect one of the main areas for improvement is the system for pupil assessment although in the last years teachers develop their skills in this direction. The analysis of the practices at “St. Paisii Hilendarski” High School indicates that the teachers currently utilize only the checking function of assessment. Assessment is not fully integrated in the educational process. It has been found that there is a weak co-relation between assessment and self-assessment, which has a negative effect on developing pupils’ skills for self-assessment. Analyzing teachers’ experience at the school as far as assessment is concerned, the following needs have been identified: expanding teachers’ knowledge of the different functions of assessment and their utilization in the educational process with the view of improving students’ performance; the application of ICT as a means for assessment and providing feedback; developing students’ skills for self-assessment. These difficulties and challenges in the assessment practice at the school necessitate the study of best practices from high-performing countries in Europe in the field of education. The aims of the project – to extend teachers’ knowledge and skills for: - Using the different functions of assessment as a means for improving students’ educational outcomes; - The application of ICT as an assessment tool and a means for feedback; - Developing students’ skills for self-assessment and self-evaluation. The project envisages thematic training for all teachers in three modules: Assessment in education and teacher professionalism; Classic and alternative forms and methods for assessment. Bulgarian and European practices; Developing assessment rubrics. After the training, eight teachers who divided evenly into four groups will be selected following clearly pre-defined criteria and they will observe the practice of evaluation in Italy, Slovakia, the Netherlands and the Czech Republic during the month of April 2016 during spring holidays for Bulgarian school or schedule agreed with partners. The teachers will be evenly divided and the visits scheduled in a way that would not cause disruptions to the school process. The best practice observations will be aimed primarily at: Methodology and techniques for assessment in the classroom; Assessment – a tool for measuring students’ progress (knowledge, skills and competencies), Non-traditional assessments (assessment in the course of informal observations; students’ work assessment, assessment of oral presentations, project work and portfolios); Information technologies – a tool for feedback and assessment; Assessment and self-assessment based on tests. Discussions with teachers from the partner schools will be held around the following themes: systemizing information for students’ progress; identifying individual student strengths and weaknesses, mapping teacher interventions that would support students’ progress. After the visits, the school will host a round-table discussion under the topic “Assessment best practices. Recommendations for novice teachers”. An important aspect of the follow-up activities will be endorsement of new assessment tools and instruments developed by the participating teachers that will enrich the assessment practice at “St. Paisii Hilendarski” High School. In order to guarantee professional support for the teachers in the application of the new tools and instruments, provisions for academic supervision have been made. The teachers who take part in the study visits will gain a new perspective on the essence of assessment and its various functions. They will develop their skills for using classic and alternative forms and methods for assessment, which not only indicate results but allow for monitoring individual performance and progress. In this sense, the delivery of the project will have an immediate impact on the students. A plan for disseminating the outcomes of the project has been designed that will ensure that all the target audiences will have access to the project’s results and practices – other local schools, the Regional inspectorate for education – Sofia District, the Ministry of Education and Science, and others.
