PORTFOLIO ASSESSMENT

STEP 6: DEVELOPING A PROCEDURE TO AGGREGATE ALL PORTFOLIO RATINGS

For each content category that theteacher includes in the portfolio, learnerswill receive a score for each draft and thefinal product. The teacher will have todecide how to aggregate these scoresinto a final score or grade for eachcontent area and, then, for the portfolioas a whole.

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.

2. Assign greatest importance to the

final draft, lesser importance to the

second draft and least importance to

the first draft.

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%.

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.

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

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

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;

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.

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

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.
