The TestTool System has the potential to have many positive impacts on both teachers and students. Teachers who use the tool can generate several tests automatically based on a pre-made database of questions. Questions in the database are scalable, so the teacher can choose the difficulty level of questions, what type of questions (either essay, multiple choice, true/false, fill-in-the-blank, matching or coding), and the amount of time the test should take. Teachers will be able to focus their time on the material covered in the exam instead of trying to write each question from scratch. The TestTool also has the benefit of reducing the amount of paper used by the university.

Students will benefit from this tool because it will offer a simpler format than some other methods of electronic test taking, as well as the option of immediate results. The system is also very beneficial to students who take programming courses, as they will be able to write code, compile and run it, and turn it in as part of the test, instead of writing bits of code by hand that never actually run.

A negative impact this tool could have is in cheating. If the teacher chooses to have the test available in electronic format for use at home, the student would be able to use the Internet, class notes, or the assistance of other students to complete the test. This may or may not matter to the teacher, but should be taken into consideration when choosing the format of the test. The TestTool System will be able to print out tests as well, so teachers concerned with cheating can choose to administer the test in a normal, hard copy format.

Data security could also be a negative impact on both teachers and students who use the TestTool. Teachers will want to be sure that test questions they have in the shared database are only accessible to other teachers, not to the students themselves. Also, students may have concerns that because the test is completely electronic they have no record of what they actually wrote, and could make the claim that the teacher is at fault for low scores. These issues will have to be addressed in the implementation of the software: the software will have to be written in such a way that the information is secure on both ends.

Another possible negative impact is the learning curve that students may have to deal with. There may be some students who will have to adjust to the new test taking system if it is administered electronically. While most students today are technologically savvy enough to be able to operate the test tool environment, there are some with no experience with computers who may have difficulties.
