The article reviews peculiarities of experimental task of the general state physics exam and its assessment. Assessment criteria of experimental tasks are analyzed. Types of experimental tasks have been defined, comparison of criteria for different types of these tasks have been made. Analysis data has been presented in the form of tables. Formulations have been offered, which concretize and supplement the criteria of the assessment. Optimization methods of subject examiners board work have been offered on the example of Novosibirsk region: algorithms of tasks evaluation of different types and schemes creating compliance of criteria to grades in the assessment of experimental tasks of all types. Examples of are shown of students’ works evaluation with the use of accompanying forms of experimental task GSE (general state exam) and offered algorithms and schemes.

Keywords: Final state examination of the school leavers on physics, experimental tasks of GSE on physics, criteria of assessment, work of an expert, Evaluation schemes of experimental task of GSE on physics.
