Conceptualizing Performance Standards for Alternate Assessments Steve Ferrara American Institutes for Research Suzanne Swaffield South Carolina Department of Education Lorin Mueller American Institutes for Research Presentation at the Eighth Annual Maryland Conference: Alternate Assessment, October 11-12, 2007

Eighth Annual Maryland Conference2 Overview Intended meaning and interpretation of performance standards Definitions of Proficient (etc.) Students with the most significant cognitive disabilities Status and growth standards Lots to consider; we haven’t addressed all considerations Comments on standard setting methods Methods must match the assessment design and intended inferences and uses of scores Articulation of standards

Eighth Annual Maryland Conference3 General principles Whatever matters for grade-level achievement assessments matters for assessments of alternate achievement standards Conception, design, development, analysis, psychometric evaluation, standard setting Achievement (aka performance) standards A coherent system Content standards, assessment tasks, score reporting scale, PLDs, cut scores on the scale

Eighth Annual Maryland Conference4 Definitions of Proficient (etc.)

Eighth Annual Maryland Conference5 Features and considerations for definitions of Proficient Are appropriate for all participating students Are aligned with the extended standards and the assessment Are reasonable and rigorous Differentiate expectations across performance levels and grade bands Are articulated across grade bands Relate sensibly to modified and grade-level achievement standards Reflect input from stakeholders

Eighth Annual Maryland Conference6 Achievement construct definitions represented by the assessment and the PLDs Reading E.g., Decoding and comprehending only? Listening and comprehending? Writing E.g., Physical act only? Creating a permanent record? Mathematics conceptual understandings and skills Science conceptual understandings and skills

Eighth Annual Maryland Conference7 Approaches to defining and differentiating levels of performance in PLDs Descriptions of performance that are moderately explicit about assessment tasks Descriptions of performance that are highly explicit about assessment tasks Descriptions of the amount of understanding and skill Descriptions of quality, frequency, or consistency of performance of specific skills Descriptions of amount of achievement progress in relation to alternate content standards

Eighth Annual Maryland Conference8 Moderately explicit references to assessment tasks ELA, Proficient The student interacts purposefully with literacy materials and demonstrates some reading strategies. When a story is read or signed, the student knows what the story is about and can answer who, what, where, and why questions; make predictions based on cause and effect; and use prior knowledge to relate to the story.

Eighth Annual Maryland Conference9 Highly explicit references to assessment tasks Reading, Proficient (and under revision) The student identifies signs and symbols; identifies letter sound relationships; blends sounds to make words; identifies a detail using pictures, symbols, or words from a story read aloud; identifies own name in print; and displays an understanding of print directionality.

Eighth Annual Maryland Conference10 Amount of achievement progress in relation to alternate content standards ELA, Proficient If there is evidence of progress [in relation to the grade-level content standards] in three data collection periods and increased complexity in two of three periods, the student progress score is Proficient.

Eighth Annual Maryland Conference11 Very different In how they Define Proficient Differentiate Proficient from other levels Relate to grade-level PLDs In what it means to say a student has achieved the Proficient level

Eighth Annual Maryland Conference13 Growth standards SC-Alt growth standards project supported by a MARS grant Suzanne Swaffield, SDE Scott Marion, Marianne Perie, Center for Assessment AIR From Ferrara S. (2007). Standards for proficient achievement growth for South Carolina’s alternate assessment, SC-Alt. In S. Davies (Organizer), Vertical Integration of Benchmarks and Standards: Including Alternate Assessments in Evaluating Growth. Presentation at the National Conference on Large-Scale Assessment, Nashville.

Eighth Annual Maryland Conference14 Students with the most significant cognitive disabilities Communication level is pre-symbolic Instructional focus likely to be on awareness of surroundings and others focusing on the activity task at hand May not reach Proficient or get out of the lowest performance level during their school careers Status standards are not appropriate and relevant Fairness and validity concerns What to do about that is an open question

Eighth Annual Maryland Conference15 Growth and status standards Status standards One score point on an alternate assessment score scale represents Proficient performance Not a big problem for most alternate portfolio assessments Limitation for other alternate assessment approaches: some students may not get there during their school career Growth standards A fixed amount of achievement growth on the alternate assessment score scale represents Proficient performance

Eighth Annual Maryland Conference16 The concept of Proficient achievement growth A growth (or difference) score on the SC-Alt score scale Learning progressions to guide, illuminate, and support development of the growth PLDs and identification of growth scores that will represent Proficient growth

Eighth Annual Maryland Conference17 Achievement growth for students with significant cognitive disabilities Significant challenges How much growth in academic achievement can reasonably be expected in one year? What do learning progressions look like for students with significant cognitive disabilities? Should we consider different expectations and progressions for different groups of students? Approaches to responding to these questions Expert opinion: academics, teachers Test score analysis Systematic data collection focused on learning progressions

Eighth Annual Maryland Conference18 Gain scores Descriptive Statistics for Gain Scores Grade BandNMeanSD Note field test, 2007 operational administration. Score scale mean and SD are ~500, ~80.

Eighth Annual Maryland Conference19 Learning progressions Committees of regular and special education teachers drafted learning progressions for extended content standards The learning progressions idea comes from task analysis in special education (and elsewhere) This is similar to the NRC call to develop models of learning and development (Knowing What Students Know) as part of the assessment design, development, and validation process

Eighth Annual Maryland Conference20 Learning progression: Measurement, grade band 3-5 Attend to/manipulate object to investigate length and weight Match objects by one attribute (length, height, weight, volume) Sort/classify objects by one attribute (length, height, weight, volume) Identify instruments used for measurement (i.e., ruler, scale, clock, thermometer, calendar) Match instrument to its function (check all the student knows) Use non-standard units to measure (e.g. use paperclips to measure length) Use instruments for measurement (check all the student can use) Match coins to coins Match coins to pictures of coins Sort coins Identify coins Match each coin to its value

Eighth Annual Maryland Conference21 Data collection Teachers will collect evidence of student progress in assigned LPs (N=9) in three windows this school year Students Low and moderate gains (i.e., 1-40 scale score points) between 2006 and 2007 Pre-symbolic and early symbolic (N=55) Standardized data collection with flexibility LP matrices to record nature of evidence and level of support

Eighth Annual Maryland Conference22 Definition of “Proficient Growth” Use status PLDs, student gain scores, and evidence of growth on LPs to write definitions of “Proficient Growth” Expect to see vertical and horizontal growth Intended uses of the definition Communicate expectations for the growth of achievement of students in a school year Guide interpretation of performance of students on SC-Alt Use in conjunction with status standards (not for AYP) Set a growth “cut score”

Eighth Annual Maryland Conference23 “Proficient Growth” (cont.) In standard setting The definition of Proficient growth will describe reasonable expectations for growth in each LP Each LP defines an extended standard Reasonable expectations for growth described in the PLDs and represented by the cut scores will have conceptual, empirical, and judgmental bases Different growth expectations for most significantly cognitively disabled students?

Eighth Annual Maryland Conference24 Standard setting methods and alternate assessment designs

Eighth Annual Maryland Conference25 Portfolio assessments Evidence of Proficient performance is in collections of evidence Proficient often is defined by improvement over the data collection periods in terms of quality or frequency of performance and level of support Body of Work is an obvious choice Profile methods may be worth considering Other widely used methods probably precluded by limited score scales

Eighth Annual Maryland Conference26 Rating scales and other scaled assessments Longer score scales enable consideration of a range of methods (e.g., Bookmark, Angoff, ID Matching) Choice of an appropriate method should consider the score scale, the rating/assessment tasks, and the intended interpretations For example: Requirements for setting performance standards for a rating scale with and without supporting collections of evidence may differ

Eighth Annual Maryland Conference27 Growth standards The need to consider evidence to illustrate how much learning is reasonable to expect probably precludes item-based methods (e.g., Bookmark, Angoff, IDM) The small amount of evidence that is feasible to collect probably precludes BoW We may try the up-and-down method

Eighth Annual Maryland Conference28 Bottom line We typically go with what’s tried and true Can’t hurt—and it’s wise—to be a little more thoughtful About matching the method with the assessment design and intended interpretations of student performance About burden and cost Summary of methods and test formats and a lot more: Perie (2007) alternate_achievement_standards.pdf
