4 Content CHC theory test blueprint-based content analysis Both broad and narrow abilities accounted for in test specifications Construct Divergent growth curves (developmental evidence) Confirmatory factor analysis (internal/structural) evidence Test and cluster intercorrelations Convergent/discriminate validity evidence Concurrent 11 special studies (775 additional subjects) Comparison to tests measuring similar constructs Validity Evidence

5 WJ III Math Clusters: Math Calculation

6 Requires calculation of problems ranging from simple addition facts to calculus (uses SRB) Basal/Ceiling Rules: 6 lowest correct/6 highest incorrect Skipped items are scored as a “0” Do not point out signs Accept reversals but not transposed numbers Clusters Broad Mathematics Math Calculation Skills Academic Skills Total Achievement Broad Ability Mathematics (Gq) Narrow Ability Mathematics Achievement ACH 5 Calculation

7 Calculation Examiner Tips If subject responds incorrectly to both sample items, testing may be discontinued. Score test “0.” Do not penalize for poorly formed numerals. Be sure to complete all queries in Test Book. Sample A: Make the number “one” in this box = = = = x x 7

8 Requires rapid calculation of single-digit addition, subtraction, and multiplication facts (uses SRB) Begin with Item 1/End with 3-minute time limit Skipped items are scored as a “0” Do not point out signs Discontinue if 3 or less correct after 1 minute Clusters Broad Mathematics Math Calculation Skills Academic Fluency Total Achievement Broad Ability Mathematics (Gq) Narrow Abilities Mathematics Achievement Numerical Facility ACH 6 Math Fluency New

9 Math Fluency Examiner Tips Do not penalize for poorly formed or reversed numbers. Record exact finishing time if subject finishes early or examiner exceeds time limit. Scoring overlay is provided.

10 WJ III Math Clusters: Math Reasoning

11 WJ III NU Tests of Achievement Test 10: Applied Problems –Requires comprehending the nature of a problem, identifying relevant information, performing calculations, and stating solution –No reading is required

12 WJ III NU Tests of Achievement 15. If Maria ate one of these suckers, how many suckers would be left? _______________________________ 30. Jay’s car holds fifteen gallons of gas. Yoshi’s car holds ten gallons of gas and Ellen’s car holds twenty gallons of gas. How many more gallons does Jay’s car hold than Yoshi’s car? Jay: 15 gallons Yoshi: 10 gallons Ellen: 20 gallons

13 WJ III NU Tests of Achievement Test 18: Quantitative Concepts –Requires applying mathematical concepts and analyzing numerical relationships (use Subject Response Booklet) –Broken into two subtests –Each item in 18B: Number Series has a 1- minute time limit

14 WJ III NU Tests of Achievement 3. What number is this? 6. Point to the largest star. Now point to the smallest star. 3 18A: Concepts

15 WJ III NU Tests of Achievement 18B: Number Series 123___ 864___ 71428___

16 Written Expression Cluster

17 Requires formulating and writing simple sentences rapidly (uses SRB) Begin with Item 1/End with 7-minute time limit Discontinue if subject has “0” on Samples B-D Any stimulus words may be read upon request 3 stimulus words may not be changed in any way Clusters Broad Written Language Written Expression Academic Fluency Total Achievement Broad Ability Reading-Writing (Grw) Narrow Ability Writing Speed ACH 8 Writing Fluency

18 A. Look at this picture and the words “good,” “cake,” and “is.” A short sentence that tells about the picture and uses these words is “The cake is good.” B. Now look at this picture and the words “pig,” “fat,” and “is.” Use these three words and any other words you need to write a short sentence about the picture. You may put the words in any order. Go ahead and do Sample Items C and D. Writing Fluency - Samples A & B A. good cake is I am going to ask you to write short sentences about some pictures. B. pig fat is

19 Score as incorrect any items skipped. Do not penalize for spelling, punctuation, or capitalization errors. Do not penalize for poor handwriting unless illegible. Response must be a reasonable sentence to receive credit. If the sentence is awkward but the meaning is clear, score as 1. Accept sentences with the understood subject you. Accept abbreviations or symbols If a word critical to the meaning is omitted, score as 0. Omission of less meaningful word is not penalized. Writing Fluency - Examiner Tips

20 Writing Fluency - Scoring Items He is dropping a dime in the bank. They are running the race again. I want to use the toy truck. The light is shining from the window.

21 Requires writing sentences in response to a series of demands that increase in difficulty (uses SRB) Use Suggested Starting Points Administer Block of Items Administer additional block of items if score falls in shaded area of scoring table Clusters Broad Written Language Written Expression Academic Applications Total Achievement Broad Ability Reading-Writing (Grw) Narrow Ability Writing Ability ACH 11 Writing Samples

22 Examiner Tips Use Scoring Guide in Appendix B of Examiner Manual. Items may be scored 2, 1.5, 1,.5, or 0 even if no example is shown in Scoring Guide. Score is based on one block even if additional blocks were administered. Writing Samples Block of Items 1 to 6 1 to 12 7 to to to 30 Scoring Responses 2 superior response 1.5not clearly a 2, but better than a 1 point 1 standard response.5 not clearly a 1, but better than a 0 0 inadequate or illegible

23 Examiner Tips Do not penalize for punctuation, capitalization, spelling, or usage errors except when indicated otherwise. Words may be read upon request. Do not spell any words for subject. Writing Samples 1. This says, “My name is________.” Write your name here. 7. This woman is a queen. Write a sentence that tells what this man is. 13. Write one good sentence that tells what is happening in this picture and what could happen next. 19. Write one sentence about a boy finding a lost dog. Include the words “who found the” in the middle of your sentence. 30. Write a good sentence using the words “despite her anger.”

24 Writing Samples - Scoring Items He can’t see ware to sit. Add eggs. Bothe the lamp & the sun are sorsus of lite.

25 Writing Samples - Scoring Items Examiner Tips Do not ask subject to read response for purpose of scoring. Response must be legible enough to be read by adult without knowledge of item content. I like to snowbored, skee, and play video games. It’s riskee to dive into a pool of unnoan depth becuz you mite misjuge your dive and, konsukwently, brake your nek. He gets a retainer but it’s not the thing you put in your mouth.

26 Writing Samples - Examiner Tips Severe grammatical or usage errors - reduce score by 1 point (omission of critical words, extremely awkward sentences) Multiple Sentences - Select and score the one sentence that most closely meets tasks demands. Inappropriate Content - Responses that have little to do with the requested task are scored as 0. Misinterpretation of Picture - Ignore and score response according to item criteria. Two Raters - Two independent raters score items and resolve any score differences of more than 1 point. Average the two scores to obtain final number correct. Round scores - ending in.5 to nearest even number (15.5 = 16, 16.5=16)

27 Adjusted Item Blocks 4 1. Began with Items Number of Points = Find 22 in column for Items See Note 2 5. Administer Items Base score on Items 7-18

28 Oral Expression Cluster

30 Story Recall - Examiner Tips Pause the audio recording after each story so the subject can respond. In the Test Record, place a check mark over each element recalled. (elements are separated by slash marks /) Elements that are bold must be recalled exactly. Other elements can be synonyms or paraphrased. If necessary, stories can be presented orally. If Test 12 Story Recall-Delayed will be administered, do not tell subject that stories may need to be recalled later.

(3) Continuation Rules If subject has 3 or fewer points on Stories 1 and 2, testing may be discontinued. If subject has 4 or more points on Stories 1 and 2, administer Stories 3 and 4 unless already administered. Sample Responses 3 Points Possible

32 Story Recall - Story 2 Mary / has a dog./ He loves to ride / in the car,/ but he hates to take a bath./ Score these responses: (5 points possible) He doesn’t like taking baths. Mary’s dog loves to ride in the car. Her dog hates baths but he loves riding in the car.

33 Story Recall - Story 5 Rick / got some glow-in-the-dark/ stars / for his sixth birthday./ He wanted to put them on his bedroom / ceiling./ He wanted to put them in his bedroom. (1) Rick got some glowing stars for his birthday. (2) He put some glow-in-the-dark stars on his bedroom ceiling. (4) Continuation Rules If subject has 8 or fewer points on Stories 5 and 6, administer Stories 3 and 4 unless already administered. If subject has 9 or more points on Stories 5 and 6, administer Stories 7 and 8 unless already administered. Sample Responses 6 Points Possible

34 Story Recall - Story 6 The dinosaur / at the museum/ was over 20 feet / tall./ Many people came to see it. / Some small / children / were scared./ They thought it was real./ Score these responses: (9 points possible) They were afraid of the dinosaur. At the museum there was a 20 foot tall dinosaur. The little kids were scared. They thought it was real.

35 Story Recall - Story 6 The dinosaur / at the museum/ was over 20 feet / tall./ Many people came to see it. / Some small / children / were scared./ They thought it was real./ Score these responses: (9 points possible) They were afraid of the dinosaur. At the museum there was a 20 foot tall dinosaur. The little kids were scared. They thought it was real.

36 Enter Date & Time. Place check mark over each element recalled correctly. 2 3 Record points for each story and each set of stories Follow Continuation Instructions. Bold words must be recalled exactly. 5 3 or fewer points: Discontinue testing. 4 or more points: Administer Stories 3 and 4.

37 Requires naming pictures (familiar to less familiar) Use Suggested Starting Points Basal/Ceiling Rules: 6 lowest correct/6 highest incorrect Point to picture or part of picture as directed Test by complete pages Clusters Oral Language-Extended Oral Expression Broad Ability Comprehension-Knowledge (Gc) Narrow Abilities Language Development Lexical Knowledge ACH 14 Picture Vocabulary
