Months always have 30 days and years (of course) have 12 months). Always double check your work.

Standardized Diagnostic Testing

• When to Use Diagnostic Tests • Instructional Level • Informal Instruments • Probes • Direct Measurement • Domains

Individualized vs. Group Tests

Individual versus Group?

Individual • Special education

eligibility • Determine goals and

objectives for IFSPs, IEPs

• Progress monitoring • May be more reliable

for certain students

Group • Determine mastery of

curriculum standards • Determine if teachers

are effective (value added) • Controversial but

happening! • Accountability and

general school planning

• May be less reliable for certain students

Test Interpretation • Analyze test scores • Are scores above

average, average or below average?

• Do the scores yield any instructional information?

• Compile with other data

• Maintain confidentiality

• Is there a pattern of strengths and weaknesses? • e. g. Areas of learning

disability? basic reading, reading fluency, reading comprehension?

passages and respond to comprehension questions

Reading Comprehension Similar to WIAT-III

Sample Maze Activity Norm-referenced tests are standardized (without/on/for) a clearly defined group, termed the (test/sample/norm) group, and scaled so that each (score/instrument/variance) reflects a rank within the (evaluation/reliability/norm) group. Psychologists have developed norm-(standardized/referenced/rated) tests to assess, for example, (height/attitude/intelligence), reading, mathematics, writing, etc. Although we (aren’t/are/is) fortunate in having a choice of (poorly/haphazardly/well)-standardized and psychometrically sound tests (without/above/with) which to evaluate children, some (numbers/tests/practitioners) do not meet acceptable psychometric standards. (Passage from Sattler, 2001)

Nelson-Denny Reading Test

substitution, and reversal to manipulate sounds in words.

Spelling of Sounds Similar to WJ-IV

• Rhyming: “What rhymes with go?”

• Deletion: “Say cowboy without saying boy”

• Substitution: “Change /s/ in sun to /f/.”

• Reversal: “Listen to the sounds in the word pot – /p/ /o/ /t/. Now you say the sounds backward.”

Other Measures that Assess Phonemic Awareness

• CTOPP-2 • Durrell-2 • ERDA-2

• PAL-2 RW • TOWRE-2 • TERA-3

• Kaufman Tests of Educational Achievement (KTEA III) • Letter and Word Recognition subtest • The examinee is asked to point to or name various

letters, sounds, and words.

Letter Word Recognition Similar to KTEA III

Test Bias

• Scores from a test should not provide a systematic advantage to a particular group or subgroup based on irregularities in test content, administration, or interpretation

• If a test produces such an unfair advantage it is said to be biased against the group that is disadvantaged (Payne, 2003)

Evidence of Test Bias

• a) Does the test assess the same content for all the groups using it?

• (b) Are the constructs assessed by the test measured consistently for all groups using it?

• (c) Does the test predict (later achievement) as well for all the groups using it?

• (d) Does the test provide equally useful instructional information for all groups using it?

Avoiding Bias

• Expert judgment • Statistical analyses: Are the constructs assessed

the same across different groups (e.g., gender, race, SES level?)

• Remember tests that are not inherently biased may be misused (e.g., use of test in English for students with limited English skills)

Selecting Formal, Individualized Instruments

• Consider test characteristics • Consider psychometric properties • Consider needs of children, classrooms, schools,

or systems • Determine whether a group or individualized test

is needed

Special Considerations for Formal, Individual Assessment of Adult and English Language

Learners

Tips for Formal, Individualized Assessment of Adult Learners • Text Box 6.7 • Assess adult learners’ educational histories, background

experiences, and interests as well as specific reading skills. • Multiple assessments will likely be needed to provide complete

information about adult learners’ reading strengths and weaknesses.

• Ensure that the test used with adults is standardized on that population.

• Put adult learners at ease; establish rapport and a purpose before launching into formal testing.

• Using grade equivalent scores, and to a lesser extent age equivalent scores, is problematic due to ease of misinterpretation of these score, and their psychometric limitations.

Tips for Adults cont’d

• Tests should include item content appropriate for adults, rather than young students, even though the difficulty level of the content may be low in order to achieve a reasonable test floor.

• Consider entering your test data and using the instructional skills profile available at the Adult Reading Components Study website: https://lincs.ed.gov/readingprofiles/resources.ht m

Tips for Formal, Individualized Assessment of English Language Learners

• Text Box 6.8 • Users should follow standards set for test administration,

scoring and interpretation in general and for ELL and other diverse learners as developed by experts. Many of these standards are reproduced in Chapter 6; some of the most relevant are reproduced in this Text Box in abbreviated form.

• Be aware that an ELL student’s formal test scores will be compared to students in the U.S., who may not resemble the ELL in background, culture, knowledge, etc.

• Related to Number 2 above, an ELL’s scores on formal tests may be depressed because of cultural, linguistic, and knowledge differences.

Tips for ELLs cont’d • Do not administer a language-loaded test for ELL

examinees unless the language content in the test is the focus of assessment.

• Related to Number 4 above, if a student’s English language proficiency is the target of assessment English language- loaded tests (i.e., English reading tests) are appropriate

• Ensure that the test does not contain item content that may be offensive in the ELL’s home country or culture.

• Ensure that reliability and validity of the test have been established for ELLs.

• Ensure that the items are not biased against ELL learners by evaluating recommendations from expert panels.

Tips for ELLs cont’d

• Ensure that items are not biased against ELL learners by examining evidence from statistical techniques designed to determine bias.

• When possible, use an examiner who can communicate in the ELL’s native language to establish rapport and aid in administering the test.

• Be aware that an ELL’s progress in learning a second language and ability to understand test demands may be limited by negative transfer from the native language.

• Reduce importance of speeded performance on scores; some cultures do not value speed.

• Ensure that the test only measures what you intend to measure (i.e., specific types of reading skills) and not some irrelevant content.

Tips for ELLs cont’d

• If your ELL students score below the mean, ensure that if mean differences occur, the differences are not the result of bias.

• Use ample teaching items to ensure that ELL learners understand the task demands.

• Using grade equivalent scores, and to a lesser extent age equivalent scores, is problematic due to each of misinterpretation of these score, and psychometric limitations.
