I used this self assessment chart at the end of the school year to prepare for state testing review. Students reflected on the year's I Can statements, and then I used the data to group students in various review centers and to plan which skills to review whole group.
These I Can statements are based on the Tennessee Third Grade Science Standards. This in Word document form in case you would like to edit the instructions or assessment columns. This chart can also be kept in student binders and they can reflect on each standard as it is covered throughout the year! Columns could be changed to allow for pre-assessment before the unit and reflection after the skill has been taught.
