This case study is conducted to focus on the reliability of assessment of portfolio. The data was gathered with the guide of a primary school science and technology teacher from portfolios of three students. These portfolios were evaluated by the teacher who has prepared them and plus two other science and technology teachers which makes the total of three teachers. Teachers assessed portfolios as very good (4), good (3), medium (2), can be improved (1). The grades that teachers have given for the portfolios were assessed with a scale made by the researchers and medium reliability was concluded at the end. It is believed that more accurate evaluation would lead to a higher level of reliability. (C) 2009 Elsevier Ltd. All rights reserved
