Observation Survey of Early Literacy Achievement (OSELA)
Reading

Summary

An Observation Survey of Early Literacy Achievement comprises six systematic, standard observation tasks developed in research studies. The tasks yield a composite and comprehensive assessment of the literacy performance of young learners. All tasks have the qualities of sound assessment instruments with reliability and validity and discrimination indices established in research. Children are assessed individually by a specially trained teacher. The Observation Survey tasks are designed to allow children to work with the complexities of written language and allow the examiner to be confident of characteristics of good measurement instruments: a standard task; a standard way of administering the task; ways of knowing when we can rely on our observation and make valid comparisons; and a task that relates to real-world tasks (content validity). Because young children begin literacy learning and instruction in early grades with individually unique knowledge and confusions, assessment of beginning reading and writing should inform the examiner of literacy behaviors along several dimensions of learning. Therefore, early assessments must be wide-ranging, with tasks to observe • Concepts about print (how print encodes information) • The reading of continuous text • Letter knowledge • Reading vocabulary • Writing vocabulary • Phonemic awareness and sound-symbol relationships It is important to know how learning is proceeding in each of these areas and to identify problems early. No one task should be used in isolation because it may assess only one aspect of early literacy behavior. Therefore, all six tasks of the Observation Survey are considered as a composite when screening and selecting children for Reading Recovery (a literacy intervention for first graders who are struggling). Because of the comprehensive nature of the assessment of each individual, results are used for screening, to guide teaching, and to monitor progress

Please describe the scoring structure. Provide relevant details such as the scoring format, the number of items overall, the number of items per subscale, what the cluster/composite score comprises, and how raw scores are calculated.
Raw scores are converted to stanines and all six tasks are considered as a composite to identify children who need a literacy intervention. For the composite measure submitted for approval as a screening tool, and for which all of the psychometric information submitted under Section III was based, the raw scores on the six tasks for each student are summed to compute a total raw score. Each student’s total raw score is converted to an IRT-based scale score that can range from 0 to 800 points. The IRT-based scale scores were derived by treating each task as a polythomously-scored item, and the six tasks were scaled based on a partial-credit Rasch model using the Winsteps computer program. Separate random samples of student task responses from either Fall 2009, mid-year (late December 2009 to early February 2010), or Spring 2010 were used as data to create the unidimensional scale that reflects literacy growth.
Describe the tool’s approach to screening, samples (if applicable), and/or test format, including steps taken to ensure that it is appropriate for use with culturally and linguistically diverse populations and students with disabilities.
The six tasks of the Observation Survey are used to screen first graders in general education classrooms and to identify those who are experiencing difficulty with literacy learning. Based on the scores on all six tasks, the lowest achievers are selected for the Reading Recovery intervention (a 12-20 week of intensive one-to-one teaching by a specially-trained teacher). [See information in the next box for a brief description and maximum scores for each task.] The Observation Survey is administered individually to children perceived by their first-grade classroom teachers as the lowest literacy achievers in their classrooms and serves as the screening process to identify the lowest achievers. The tester is a specially trained teacher. For each task, the tester records the raw score and the stanine. In consultation with the school team and the Reading Recovery teacher leader, the children with the lowest stanine scores across the Observation Survey are identified, without regard to cultural or linguistic diversity or disabilities. The intervention is intended to serve the lowest-performing first graders in regular classrooms to raise their literacy achievement so they can benefit from classroom instruction. For the few children who do not reach average performance as a result of the intervention, Reading Recovery serves as a prereferral intervention, providing information for future educational actions. For additional information about screening and selecting children for Reading Recovery intervention services, see Chapter 5 in Changing Futures: The Influence of Reading Recovery in the United States, or an article entitled “Selection of Children for Reading Recovery: Challenges and Responses” in the Fall 2005 issue of The Journal of Reading Recovery.

Describe the criterion (outcome) measure(s) including the degree to which it/they is/are independent from the screening measure.
The Slosson Oral Reading Test-Revised is a series of graded word lists. It is a standardized measure that is completely independent of the OS screening measure
Do the classification accuracy analyses examine concurrent and/or predictive classification?

Describe when screening and criterion measures were administered and provide a justification for why the method(s) you chose (concurrent and/or predictive) is/are appropriate for your tool.
Describe how the classification analyses were performed and cut-points determined. Describe how the cut points align with students at-risk. Please indicate which groups were contrasted in your analyses (e.g., low risk students versus high risk students, low risk students versus moderate risk students).
We used the pROC package as described in Appendix A of the FAQ for the classification analyses. The Slosson Oral Reading Test-Revised manual does not provide end of first grade norms so we used a random sample of 8200 students to determine the cut point for the bottom 15%. We used this cut to identify children in need of intensive intervention at the end of first grade. None of these students had participated in the Reading Recovery intervention during first grade. The cut point on the Observation Survey Total Score in the fall was based on the 80% sensitivity level in the ROC analysis.
Were the children in the study/studies involved in an intervention in addition to typical classroom instruction between the screening measure and outcome assessment?
No
If yes, please describe the intervention, what children received the intervention, and how they were chosen.

Observation Survey of Early Literacy Achievement: Text Reading Level

Classification Accuracy

Select time of year
Describe the criterion (outcome) measure(s) including the degree to which it/they is/are independent from the screening measure.
Observation Survey of Early Literacy Achievement, Text Reading Level is a standard set of passages that increase in difficult. The highest text level the child is able to read with 90% accuracy or higher is the child’s Text Reading Level (See attached article by D’Agostino et al., 2016.) Text Reading Level is one component of the fall screening measure, but no child identified for intervention in the fall would read passages above Text Level 6, so the Text Level 18 passage is completely independent of the screening measure.

CONTENT VALIDITY The content of all tasks of the Observation Survey aligns with national reading standards and is well-documented in research. Developed for use in early-grade classrooms, Observation Survey tasks each “assess an area of literacy knowledge which provides an essential foundation for progress in reading and writing. The content of the tasks represents what is actually taught in the classroom” (Clay, 2002, 2006, p. 159). Denton et al. (2006) say that the wide implementation of the instrument suggests there is agreement about the content validity of the Observation Survey. All of the tasks in the Observation Survey represent real-world tasks and literacy instructional expectations in earlygrade classrooms. Support for content validity of each task is summarized below. Letter Identification Concept Assessed: Letter Knowledge Content Validity: It is common practice in the early grades for teachers to find out how many letters a child knows and if the child can visually distinguish letters one from another. In this task, all lowercase and uppercase letters (plus print forms of ‘a’ and ‘g’) are assessed. Children can respond with the letter name, a sound the letter makes, or a word beginning with the letter. Because this is a closed knowledge set, the task is most valid during the time a child is acquiring letter knowledge. The content represents what is actually taught in classrooms. Ohio Word Test Concept Assessed: Word Knowledge (Reading Vocabulary) Content Validity: Word knowledge correlates strongly with text reading performance. And teachers of early readers seek ways to document the number of words a child knows and how this developing knowledge changes across time. The content of this task represents typical classroom expectations. This task is structured to sample words that the children have had some opportunities to learn — words that occur frequently in their texts in school. Word lists (lists of 20 words) are drawn from the Dolch list of highfrequency words. Three equivalent lists are available. Because these lists include very high-frequency words, the task is most valid over the period when a child is acquiring an initial reading vocabulary. In addition to information about a child’s knowledge of words in isolation and how this knowledge develops over time, the teacher can learn how a child works with words through attempts and self-corrections. Concepts About Print Concept Addressed: Print Knowledge (what children know about the way spoken language is represented in print) Content Validity: Conventions used for printed language must be learned so the child can attend to the essential visual information on the page. The task assesses a child’s current knowledge of 24 print concepts. Content validity is supported through the use of a specially designed book that allows the child to demonstrate knowledge of print concepts in an authentic setting. Writing Vocabulary Concept Addressed: Writing Vocabulary (a child’s personal resource of known words) Content Validity: In this task, the child writes words he knows for a period of 10 minutes. The teacher may prompt the child in various ways to think of other known words. The score represents the number of words written independently and also serves as a screen on the child’s visual attention to print, sound sequence, motor control, and useful approximations. This task represents classroom instructional expectations. Hearing and Recording Sounds in Words Concept Addressed: Phonemic Awareness and Letter/Sound Relationships Content Validity: The importance of phonemic awareness and representing phonemes with letters or clusters of letters is well documented in the research literature. Teachers can use the score on this dictation task (with a sampling of 37 phonemes) as an indicator of a child’s developing knowledge in this area. This task measures classroom instructional practices. The teacher dictates a passage (five forms available) and asks the child to say the words slowly and write letters to represent the sounds. Each phoneme recorded in a way that is acceptable in English is counted. Because this is a closed knowledge set, the task is most valid over the period when a child is acquiring this knowledge and before the words in the passage become part of a child’s known writing vocabulary. Running Records of Text Reading Concept Addressed: Instructional Reading Level for Reading Continuous Text (also child’s behaviors while reading real books) Content Validity: The score on this task represents the highest text level (from texts representing a gradient of difficulty) that a child reads at 90% accuracy or higher. The task is an authentic assessment of the reading of continuous text. The testing packet used for Reading Recovery in the United States has been shown to be a stable measure of reading performance that represents escalating gradients of difficulty. Evidence from research and classroom practice confirms that text difficulty relates to a reader’s developing competencies. For learning to occur, the difficulty level of reading materials should present challenges from which the child can learn—texts that are not too hard or too easy. As the child reads the texts, the teacher uses established conventions to record behaviors in order to analyze the child’s reading behaviors.
