Formal and Informal Reading Diagnostic Assessments
A students ability to read the English language can be influenced by a number of factors. While recognizing that students represent a diverse population of varied backgrounds and experiences, teachers must consider a variety of resources to identify the specific factors that are contributing to reading challenges. No one assessment can fully diagnose the barriers to reading success that a child may be facing. After careful review of a student’s background, experiences, and prior academic performance, a teacher can then consider a number of specific assessments, including the Slosson Intelligence Test (SIT), Slosson Oral Reading Test (SORT), Basic Reading Inventory (BRI), Wepman’s Auditory Discrimination Test (WADT), Test of Visual Perceptual Skills (TVPS-3), and The Stroop Test.
The Slosson Intelligence Test (SIT) is designed to estimate the individual cognitive ability and verbal intelligence of students, mental patients, and/or mentally handicapped individuals. The test is user friendly, low cost, and can be administered in a short amount of time, ranging from 15 to 30 minutes. The test is designed to evaluate vocabulary knowledge, general information, similarities and differences, comprehension, quantitative, and auditory memory across 187 questions categorized by age. While the test can be administered to individuals with learning disabilities and orthopedic disabilities, it is only applicable to children above age 4 and offers no differentiation past age 18. Furthermore, because the test is administered orally, it has limited applications across an increasingly diverse student population that speaks multiple languages. Finally, due to complex academic terminology, an advanced degree is recommended to successfully implement the test, limiting the population that can use it as an assessment tool. While the Slosson Intelligence Test (SIT) has both it’s strengths and weaknesses, it should only be used as an initial screening tool to determine the need for further diagnostic testing and never to make placement decisions.
Also designed by Richard Slosson, the Slosson Oral Reading Test (SORT) provides a quick estimate of target word recognition levels and decoding ability in both children and adults. The SORT is a norm-referenced assessment that provides estimates of grade and age equivalents, standard scores, and national percentiles. Students are asked to read words in sets of 20 until they are no longer able to do so correctly. Benefits of the SORT includes its quick and easy administration and availability in Spanish, Braille, and large print. One of the biggest advantages is the test’s alignment with Common Core State Standards, assuring that performance on the test is a valid indicator of grade level equivalence. Like the SIT, the SORT has a number of significant disadvantages. One of the biggest weaknesses is it’s lack of a comprehension component, particularly given the recent push for close reading and text evidence. Furthermore, the SORT fails to assess the ability to determine grapheme/phoneme relationships and lacks sensitivity for cultural differences. The Slosson Oral Intelligence Test (SORT) should be used for screening only and combined with observations and additional diagnostic assessments to make deterministic placement decisions.
Perhaps the most widely used reading diagnostic assessment is the Basic Reading Inventory (BRI), which is designed to identify reading behaviors and ability, including word identification, fluency, and comprehension. The BRI assesses a student’s individual, instructional, and frustration levels through the reading of grade specific word lists, short stories and passages, and ability to answer text dependent comprehension questions. Considering performance in the above mentioned areas, the BRI goes on to recommend targeted interventions that address the challenges a student may be facing. Benefits of the BRI include its user friendly administration and progress monitoring ability by providing multiple sets of grade specific word lists. Although the BRI does not specifically assess phonemic awareness, it is a comprehensive manner of assessing rate, accuracy, and prosody in reading. Cautions to consider when administering the BRI include the individual interpretation of comprehension responses along with the external factors that can effect the results when the test is administered over multiple days. Because the BRI requires more time than most of the other assessments, administration in one session can be influenced by student attention and stamina, and administration across multiple days can be affected by an abundance of at-home challenges like lack of sleep and proper nutrition. Even with it’s shortcomings, the BRI is still considered an effective tool to diagnose specific challenges in reading behavior and identify necessary interventions.
Wepman’s Auditory Discrimination Test (WADT) provides a measure of phonological awareness and is an accurate indicator of a child’s readiness of reading instruction. Auditory discrimination is critical to the ability to differentiate between phonemes which allows students to compare and contrast speech sounds, separate and blend phonemes, identify phonemes in words, and combine phonemes. All of these skills are critical to the development of fluency, reading comprehension, and success in future reading instruction. The Wepman’s Test is most appropriate in the evaluation of communication skills and the identification of reading difficulties and speech deficits. The test is fast, inexpensive, and easy to administer and includes retests to account for testing interference and challenges. While the norms for the test were based on a diverse student population, both culturally and socioeconomically, the test does not account for these differences in the preparation of the test material. Furthermore, the WADT lacks accommodations for students with disabilities; whereby hearing and attention deficits can skew the results.
Because visual perceptual abilities are critical to success in a number of academic activities and instruction, it is important to know which processes prove challenging for a student. The Test of Visual Perceptual Skills (TVPS-3) is used to determine visual perception strengths and weaknesses over extended periods of time in student’s ranging from age 4 to 18. The test involves the administration of seven subtests arranged in order of difficulty and includes visual discrimination, visual memory, spatial relationships, form constancy, sequential memory, visual figure ground, and visual closure. The TVPS-3 is administered in a multiple choice format with students indicating their choice orally or by pointing. As just mentioned, strengths of the test includes the child’s ability to use multiple response methods, including pointing to one of the designs on the page, saying the number of the answer choice, or by any other means understood by the examiner. For this reason, the test can be administered to children with and without disabilities. Weaknesses of the TVPS-3 include the difficult and confusing scoring process, sometimes lengthy administration, and the reliance on a child’s strong receptive language skills to complete the test. Overall, the TVPS-3 is considered a valid and reliable indicator of visual perceptual abilities that may be contributing to reading difficulties.
Used widely in clinical practice and investigation, the Stroop Test evaluates the psychological process of reading through the administration of three trials, including color naming, color name reading, and interference. The word trial requires students to read words of color name; the color trial asks students to identify the color of printed shapes; and the color-word response inhibition trial asks students to name the color in which the word is written and not the actual printed word. The Stroop Test measures a person’s selective attention capacity and skills, as well as their cognitive flexibility and processing speed ability. It is easy and quick to administer, applicable across cultures, and available in multiple translations. Unfortunately, the Stroop Test cannot be used on individuals with brain damage, ADHD, and a variety of mental disorders. Furthermore, given the use of colors to administer the test, individuals with color blindness may not produce valid test results. In the appropriate population, the Stroop Test can be used to determine the impacts of cognitive processing ability and attention capacity on reading ability and comprehension.
In conclusion, a number of diagnostic reading assessments exist to effectively evaluate a student’s skill level across all five elements of reading instruction. No one resource can be used to make deterministic and placement decisions due to the individual limitations of each assessment. Educators and/or assessment administrators must fully assess the background and individual differences amongst the student population prior to selecting the most appropriate tests under a given set of circumstances. Through the use of the most appropriate diagnostic assessments, a student’s challenges and barriers to reading ability can be identified and the most effective strategies for improvement implemented in an effective and timely manner.
