Introducing the BASI™

The BASI™ (Basic Achievement Skills Inventory)

assessments are a series of versatile, multi-level,

norm-referenced achievement tests that help

measure math, reading and language skills for

children and adults. The tests also yield criterion-

referenced information.

4

• The BASI-Survey (BASI-S) • AGES 8 to 80

The BASI™ series includes

• The BASI-Comprehensive (BASI-C) • Grades 3-12 and adults

5

BASI-Survey

• For a detailed description of the BASI-Survey, along with sample reports please open the folder labeled BASI-Survey included on the CD-ROM.

Measures in-depth academic skills – For students in grades 3-12 – To determine academic strengths– To pinpoint specific learning difficulties– To measure student progress (Form A & B)

BASI™ Comprehensive (BASI-C)

Level 1 3rd- 4th Grade

Level 2 5th- 6th Grade

Administration and scoring options

• BASI™ C administration options• Computerized with the Q Local™software• Paper & pencil

• Scoring options• Computer scoring with the Q Local™software

– Immediately upon administration– Immediately with an attached scanner (using scannable

answer sheets)

• Mail in scoring service (using scannable answer sheets)

• Hand-scoring with carbon-less answer sheets

(requires manual for look-up tables-use when a quick estimate of standard scores only is desired or is sufficient).

10

BASI-C Features

• Sensitive to Testing Time (less than 2 hrs)

14

READING

Vocabulary Measures skills in

• recognizing the meaning of words presented in isolation or out of context• identifying meanings of words within the context of a sentence• recognizing synonyms and antonyms• solving verbal analogies

Reading ComprehensionMeasures Skills in

Literal and Inferential comprehension

• Consists of passages that a student must read followed by questions relating to:– the passage’s main idea– sequence of events– details about the setting– cause and effect

relationships– predicting outcomes– drawing conclusions

15

WRITTEN LANGUAGE

Spelling • Measures students’ skills in recognizing correctly spelled

and misspelled words• Each list of words per test level includes

– sight words– commonly misspelled words– words with affixes

Language Mechanics• Measures students’ knowledge of various grammar and

syntax rules• Subtest items measure knowledge of skills such as:

– capitalization– punctuation– verb forms– tense agreement

16

MathMath Computation • Measures

knowledge of the four basic operations dealing with whole numbers, fractions, and decimals as well as the simplification of numerical expressions and algebraic equations

Math Application • Solving

mathematical problems using all basic operations:– to read and

interpret data presented visually in graphs or tables,

– to solve problems relevant to measurement principles as they relate to length, weight, volume, perimeter, and money

17

BASI Development

• Item development• Standardization sample• Psychometric properties

– Reliability– Validity

18

Item Development

• Creation of the test blue print or test specification matrix – National standards

• Item writing and review– Individuals with expertise in respective subject

areas.– Teaching experience at various grade levels– Formal item writing training and supervision.

19

BASI-CStandardization sample

• 2000 Census (normed on over 4000 students• Form A- Fall 2002• Form B- Spring 2003 • Stratification variables

– Gender– Race/ ethnicity– Socioeconomic level (Parental education)– Region

• No adult norms (only criterion-referenced scores)

21

BASI- ComprehensivePsychometric Properties

VALIDITY EVIDENCE--- QUALITY OF INFERENCES.

• Content • Relationship to:

– group achievement tests– individually administered tests

• Performance of:– Special education students– Bilingual students

22

Content validity

• The most important evidence for an achievement test.

• Must be comprehensive – Sensitive to grade levels it assesses – Allow normative and criterion reference

information that will guide further assessments for progress monitoring of targeted interventions.

– Have alternate forms to allow follow up assessments.

23

Content Validity- Why bother?

24

Content validity

• National standards• Item writers with expertise in respective

subject areas.• Numerous cycles of item reviews• Documentation and detail reporting of

what was included• Content matching analysis with other

tests.

Norm-referenced scores

Criterion-referenced information

Individual student report sample

32

Standard scores have a mean of 100 and a SD of 15 to facilitate comparison with individually-

administered achievement tests and IQ tests.

33

Interpretive text

highlights scores to

briefly explain

their meaning.

34

Notice what happens to the report when the

test is administered

untimed.

A disclaimer appears at the

top of the report, and all the standard

scores are grayed-out.

35

However, if the test is timed,

but administered with special

accommodations, a disclaimer appears but so

do all the standard scores.

36

An optional, free Parent’s Report is included with the Student Summary

Report.

This report simply illustrates the percentile score and labels the

performance, and allows space for the examiner’s written comments.

A lengthier narrative explains the scores.

37

Q. Why bother studying test content?

– Most essential feature in an achievement test– Linking assessment to intervention

Concurrent validity

• Relationship to: – individually administered tests

• WIAT-II• WJ-III

– group achievement tests• ITBS• TABE• BASI SURVEY

42

• Individually-administered achievement tests• Woodcock Johnson III (WJ-III)• WIAT-II• WRAT-3

• Good tests, but the BASI™• covers as many or more learning standards and with more

items • correlates highly with these tests• doesn’t require one-on-one administration and therefore more

cost-effective and convenient• is just as reliable and valid (if not more valid due to in depth

content coverage)

BASI™ and other tests

43

• Off-the-shelf standardized achievement tests• Iowa Test of Basic Skills (ITBS)• Stanford 10 (SAT10)• California Achievement Test, fifth edition (CAT/5)

• Good tests, but the BASI™• is administered in about half the time • has a higher ceiling than the ITBS• is just as valid and reliable• does not require a locator test • collects NCLB demographics for AYP• is a better value (no hidden costs, free Parent’s Report)• can be administered on-screen and scored locally

48

Steps • Administer the BASI Form A as early in the year as

possible.• Use the paper or Q-Local administration• Print the individual student reports• Review each student’s performance

– Identify areas in need of… (remediation, enhancement)– Inform the student and parents– Inform other stakeholders (principal, others)

• Create classroom reports– Export the Q-Local data

• Consider intervention or remediation plans– Individual students– Classroom

49

BASI™ Comprehensive reports

• Student Summary• Single page report for

– the student & teacher– Standard score– Criterion Referenced

infor.• Parent’s report

– Optional and Free

50

Interpretation and inferences

• with data• with procedures commonly used

– Identification of statistically significant differences

– Comparisons with other tests

Classroom reports

• 1. Export assessment data from Q-Local• 2. Import to a data base • 3. Generate classroom or building reports

55

NCLB/IDEA reporting

NCLB Subgroup Reporting RequirementsEconomically disadvantaged students

• Students with disabilities (served under IDEA)• Students with limited English proficiency• Students from major racial/ethnic groupsIDEIA 2004• Initial evaluations (administer BASI individually or in

small groups) • Monitor student progress (Form A & B)• Annual and triennial evaluations• New transfers to building or school• Student transition to workplace or college

56

WHY the BASI ?

• Ease of administration and scoring• Content coverage• Easy to understand scores• Sensitive reports that link assessment to

intervention• Can assist with NCLB and IDEIA decisions
