Abstract-This paper presents a web-based assessment system, which supports parameterized questions, incorporating remote web services/applications, in order to use them during the evaluation process. The proposed system introduces a dynamic technique for creating a new type of parameterized web-based questions which mix static and dynamic content and thus, it operates as an integration framework, incorporating these remote web services/applications as part of the evaluation process. The technique is based on question templates, which contain the details of the remote services/applications that provide the correct answer in each question. The incorporation of remote web-based services into a parameterized assessment system, as part of the evaluation process, constitutes an advanced feature that provides new capabilities, such as flexibility and extensibility to any assessment system.
