The document discusses developing a procedure to aggregate portfolio ratings. It provides examples of averaging scores from drafts and final products to calculate an overall score. Teachers must decide whether to give equal or different weights to different parts of the portfolio. Scores can be converted to letter grades with cut-offs. The process involves specifying timelines, submission methods, storage, and access to the portfolio, as well as planning final conferences.

1. PORTFOLIO ASSESSMENT
 STEP 6: DEVELOPING A PROCEDURE TO
AGGREGATE ALL PORTFOLIO RATINGS
For each content category that the
teacher includes in the portfolio, learners
will receive a score for each draft and the
final product. The teacher will have to
decide how to aggregate these scores
into a final score or grade for each
content area and, then, for the portfolio
as a whole.

2. For Example:
In English (essay), the teacher
averaged the ratings for the two
preliminary drafts and the final one. The
next step is to develop a rule or
procedure for combining these three
scores into an overall score.
1. Compute a simple average of
three
scores.
* This method gives equal
importance in the final score to the drafts
and final product.

3.  2. Assign greatest importance to the
final draft, lesser importance to the
second draft and least importance to
the first draft.


4. If you decide to assign different
importance or weight to the products in a
content area, do the following:
1. Decide on the weight in terms of
percentage (ex. First draft – 20%,
second draft -30%, final draft – 50% of
final score). Make sure the percentages
add up to 100%.

5. 2. Take the average score for each
product and multiply that by the weight.
 Ex. Draft 1: 3.50 x 0.2 = 0.7
 Draft 2: 4.25 x 0.3 = 1.3
 Final : 3.75 x 0.5 = 1.9
 3. Add up these products .
 4. Decide how to aggregate these
scores (weight or not to weight)
 5. Assign a rating to the portfolio
as a whole.

6. GRADING SCHEMES MEANING
90 – 100 A Outstanding
80 - 89 B Above Average
70 - 79 C Average
60 - 69 D Below Average
below 60 F Failure, not at
standard

7. AVERAGE RATING GRADE
 4.4 – 5.0 A, 90 – 100
 3.6 – 4.3 B, 80 – 89
 2.6 – 3.6 C, 70 – 79
 2.0 – 2.5 D, 60 – 69
 1.0 – 1.9 F, 50 – 59

8. STEP 7: DETERMINING THE LOGISTICS
 So far, you have accomplish these
aspects of portfolio design:
 1. specified the purpose of the
portfolio;
2. identified the cognitive skills it will
reflect;
3. Decided who will help plan it;
4. Decided what and how many
products go in it;

9. 5. specified the rubrics by which to score
it
6. develop a rating and grading scheme
 There are just a few details left.
1. TIMELINES
- learners and parents need to know
exact dates when things are due.
2. HOW PRODUCTS ARE TURNED IN
AND RETURNED
- Decide how, when, and where you
want
- your learners to turn in their
products.

10. 3. WHERE FINAL PRODUCTS ARE
KEPT
- decide where the final products will be
stored ( at home, in the classroom)
4. WHO HAS ACCESS TO THE
PORTFOLIO?
- certainly the teacher, learners and
parents have a right to see what’s in it

11. 5. PLAN A FINAL CONFERENCE
- plan to have a final conference at the end
of the year or term with individual learners
and, if possible, their parents to discuss the
portfolio and what it says about your
learners’ development and final
achievement.
