I used Testmoz this past week in class and found it to be quite useful in simple summative assessment. This site provides an easy to use interface with all of the basic question types. Results are broken down by individual questions and by student scores. They do require a one time donation to the site to support them but then you are able make as many different quizzes and tests as you would like. Once your test is complete you can either embed the quiz on your website or provide a link to the actual quiz on Testmoz. Both options seemed to work well for me. This is definatley one to go into the teacher toolbox for me.
