Rubric: Each question (with the exception of “Client Name”) will be rated on a scale of 0-3. Writing the “Client Name” is worth only 1 point. You will also be rated on a scale of 0-4 for your participation during the 4 class sessions used to complete this activity.

0 / This response is either incoherent, irrelevant, or contains many computational errors. Appropriate diagrams are excluded.
1 / This response is essentially correct but contains no supporting or relevant information. Appropriate diagrams are either missing or are incorrect.
2 / This response is almost perfect but contains only minor errors. Appropriate diagrams are included.
3 / Perfect response. All answers are correct and supported appropriately. Responses are thoughtful and use proper vocabulary. Appropriate diagrams are included.

Note: Final submission should be typed using TNR size 12. Please email your final responses to no later than midnight on Friday February 18, 2011.

It may be more convenient to type your responses into the following table rather than the .pdf document.
