The Case for Authentic Assessment.
WHAT IS AUTHENTIC ASSESSMENT?
Assessment is authentic when we directly examine student performance on worthy intellectual tasks. Traditional assessment, by contract, relies on indirect or proxy ‘items’–efficient, simplistic substitutes from which we think valid inferences can be made about the student’s performance at those valued challenges.
Do we want to evaluate student problem-posing and problem-solving in mathematics? experimental research in science? speaking, listening, and facilitating a discussion? doing document-based historical inquiry? thoroughly revising a piece of imaginative writing until it “works” for the reader? Then let our assessment be built out of such exemplary intellectual challenges.
Further comparisons with traditional standardized tests will help to clarify what “authenticity” means when considering assessment design and use:
Beyond these technical considerations the move to reform assessment is based upon the premise that assessment should primarily support the needs of learners. Thus, secretive tests composed of proxy items and scores that have no obvious meaning or usefulness undermine teachers’ ability to improve instruction and students’ ability to improve their performance. We rehearse for and teach to authentic tests–think of music and military training–without compromising validity.
The best tests always teach students and teachers alike the kind of work that most matters; they are enabling and forward-looking, not just reflective of prior teaching. In many colleges and all professional settings the essential challenges are known in advance–the upcoming report, recital, Board presentation, legal case, book to write, etc. Traditional tests, by requiring complete secrecy for their validity, make it difficult for teachers and students to rehearse and gain the confidence that comes from knowing their performance obligations. (A known challenge also makes it possible to hold all students to higher standards).
WHY DO WE NEED TO INVEST IN THESE LABOR-INTENSIVE FORMS OF ASSESSMENT?
While multiple-choice tests can be valid indicators or predictors of academic performance, too often our tests mislead students and teachers about the kinds of work that should be mastered. Norms are not standards; items are not real problems; right answers are not rationales.
What most defenders of traditional tests fail to see is that it is the form, not the content of the test that is harmful to learning; demonstrations of the technical validity of standardized tests should not be the issue in the assessment reform debate. Students come to believe that learning is cramming; teachers come to believe that tests are after-the-fact, imposed nuisances composed of contrived questions–irrelevant to their intent and success. Both parties are led to believe that right answers matter more than habits of mind and the justification of one’s approach and results.
A move toward more authentic tasks and outcomes thus improves teaching and learning: students have greater clarity about their obligations (and are asked to master more engaging tasks), and teachers can come to believe that assessment results are both meaningful and useful for improving instruction.
If our aim is merely to monitor performance then conventional testing is probably adequate. If our aim is to improve performance across the board then the tests must be composed of exemplary tasks, criteria and standards.
WON’T AUTHENTIC ASSESSMENT BE TOO EXPENSIVE AND TIME-CONSUMING?
The costs are deceptive: while the scoring of judgment-based tasks seems expensive when compared to multiple-choice tests (about $2 per student vs. 1 cent) the gains to teacher professional development, local assessing, and student learning are many. As states like California and New York have found (with their writing and hands-on science tests) significant improvements occur locally in the teaching and assessing of writing and science when teachers become involved and invested in the scoring process.
If costs prove prohibitive, sampling may well be the appropriate response–the strategy employed in California, Vermont and Connecticut in their new performance and portfolio assessment projects. Whether through a sampling of many writing genres, where each student gets one prompt only; or through sampling a small number of all student papers and school-wide portfolios; or through assessing only a small sample of students, valuable information is gained at a minimum cost.
And what have we gained by failing to adequately assess all the capacities and outcomes we profess to value simply because it is time-consuming, expensive, or labor-intensive? Most other countries routinely ask students to respond orally and in writing on their major tests–the same countries that outperform us on international comparisons. Money, time and training are routinely set aside to insure that assessment is of high quality. They also correctly assume that high standards depend on the quality of day-to-day local assessment–further offsetting the apparent high cost of training teachers to score student work in regional or national assessments.
WILL THE PUBLIC HAVE ANY FAITH IN THE OBJECTIVITY AND RELIABILITY OF JUDGMENT-BASED SCORES?
We forget that numerous state and national testing programs with a high degree of credibility and integrity have for many years operated using human judges:
Though the scoring of standardized tests is not subject to significant error, the procedure by which items are chosen, and the manner in which norms or cut-scores are established is often quite subjective–and typically immune from public scrutiny and oversight.
Genuine accountability does not avoid human judgment. We monitor and improve judgment through training sessions, model performances used as exemplars, audit and oversight policies as well as through such basic procedures as having disinterested judges review student work “blind” to the name or experience of the student–as occurs routinely throughout the professional, athletic and artistic worlds in the judging of performance.
Authentic assessment also has the advantage of providing parents and community members with directly observable products and understandable evidence concerning their students’ performance; the quality of student work is more discernible to laypersons than when we must rely on translations of talk about stanines and renorming.
Ultimately, as the researcher Lauren Resnick has put it, What you assess is what you get; if you don’t test it you won’t get it. To improve student performance we must recognize that essential intellectual abilities are falling through the cracks of conventional testing.
