I entered my data into the form, but when I went back it was no longer there.

If you are no longer able to access data you entered in Tk20, this may be the result of one or more of the following:

1) Use the latest version of the Firefox browser to successfully complete/save work in Tk20. The number one reason why cooperating teachers have encountered problems entering comments into the comment fields is due to the Internet browser being used. Tk20 works best using the latest version of Firefox, which can be downloaded for free here:

2) It is very important to remember to click "Save" in TWO places for each form. The first time you should click "Save" is when you reach the bottom of the form you are working on. When you click "Save" here, you will be directed back to the main list of forms to be completed. It is important to click "Save" on this screen as well. Clicking "Save" at both of these points will help to ensure your form is saved correctly.

3) The Tk20 system will "time out" after a certain period of inactivity. This is a security feature embedded in the system so that sensitive student data isn't left open on an Internet browser for an extended period of time -- just like an online bank account page will time out automatically to protect sensitive information. This is something our cooperating teachers have run into, due to the fact that some of the observation forms are very long and take a while to complete. To avoid losing data, we highly recommend scrolling to the bottom of the forms and clicking "Save" periodically -- just like you would normally do when working on any Word document or important project that requires work to be saved manually.

4) Student teachers and cooperating teachers should only click "Submit" ONCE during the semester. When a student teacher or cooperating teacher clicks "Submit" before all field experience forms are filled out and saved, the assignment will lock and it will not be possible to do any further editing. If any of your cooperating teachers or student teachers contact you about not being able to access their assignments, this is the likely cause -- they accidentally clicked "Submit" instead of "Save." If this occurs, please send an email to and we will grant an extension for the assignment.

5) Do not use the "Back" button in your browser -- only use the "Back" or "Cancel" buttons within Tk20. Using the "Back" button in your browser could cause you to lose any unsaved work.
