Use the following scale and assess yourself on how well you can completed this activity. Feel free to estimate in between
each category. Example: 2.5 if you need help on some, but can do the rest on your own.
1- Below Basic: I am having difficulty in meeting the standard. (I don’t know what I’m doing)
2- Basic:
I am approaching proficiency in meeting the standard. ( I could finish with some help)
3- Proficient: I can consistently demonstrate proficiency in meeting the standard. ( I can do this and will be able to do it
later)
4- Advanced: I can consistently exceed key concepts, processes & skills. Exceeds the standard ( I can do more
questions similar to these)
