K-12 research-based CAT and CBM reading assessment

FastBridge reading assessment suite
CAT and CBM reading assessment tools in one platform
FastBridge’s unique FASTtrack screening removes confusion about what to administer by providing easy access to recommended assessments for each grade level, based on their capacity to predict future student reading performance. It also indicates what type of reading instruction is needed.
aReading
Universal Screening | Grades K–12 | Computer-Based | Computer-Adaptive Test | Time Required: 15–40 min | Included in FASTtrack Reading
aReading is a computer-administered adaptive screener that measures broad reading ability. Developed for students in grades K–5, it targets concepts of print, phonological awareness, phonics, vocabulary, and comprehension and aligns with national reading standards. It also provides student Lexile® scores derived from a large-scale Lexile® linking study.
The FastBridge adaptive assessments produce a highly accurate indicator of overall performance with as few as 25 items. This reduces testing time up to 50% compared to traditional fixed-form assessments.

AUTOreading
Universal Screening and Progress Monitoring | Grades K–12 | Computer-Based | Curriculum-Based Measure | Time Required: 2–6 min | Included in FASTtrack Reading
AUTOreading emerged from years of research as a fully automated, computer-administered measure of decoding, word identification, spelling, and vocabulary. It includes eight individual subtests of 30 items, with two to four subtests recommended per grade level, to measure students’ accuracy and automaticity.
Subtests include: letter names, letter sounds, encoding, word identification, vocabulary, matching synonyms, decoding, morphology.

CBMreading
Universal Screening and Progress Monitoring | Grades 1–8 | Teacher-Administered | Curriculum-Based Measure | Time Required: 1–3 min | Included in FASTtrack Reading | Available in both English and Spanish
CBMreading is a research-based assessment offered in English for grades 1–8 as well as in Spanish for screening in grades 1–6 and progress monitoring in grades 1–5.
CBMReading aligns with skills included in the National Reading Panel Report (2000) and the national standards for English and Language Arts (2010). By listening to a student read, a teacher can assess key skills, including phonemic awareness, phonics, and fluency.
Substantial research evidence demonstrates that CBMreading is a robust indicator of reading development and a useful predictor of student performance on state tests.

earlyReading
Universal Screening and Progress Monitoring | Pre-K–1 | Teacher-Administered | Curriculum-Based Measure | Time Required: 1–4 min | Included in FASTtrack Reading | Available in both English and Spanish
earlyReading is a suite of CBM assessments measuring essential reading skills that typically develop in grades K–1. It can also be used as a valid screener in pre-K programs and to support students at-risk above Grade 1.
The assessment suite includes a continuum of 13 subtests that is typical of early reading skill development for most students. Based on research, FastBridge recommends four subtests (three for Spanish) that vary across grades K–1 for screening. Remaining assessments may be used to further evaluate skill deficits.

COMPefficiency
Universal Screening and Progress Monitoring | Grades 2–8 | Computer-Based | Curriculum-Based Measure | Time Required: 7–12 min | Lab Status*
COMPefficiency measures the quality and efficiency of the comprehension processes that occur during reading (e.g., main ideas, sequence of events, literal and inferential comprehension) and the quality of the comprehension after reading (e.g., qualities of the mental representation).
Students read sectioned text passages with brief true-false questions that measure literal and inferential comprehension. After reading the entire passage, students respond to multiple-choice questions designed to evaluate understanding of the main idea, sequence of events, and reasonable inferences that can be drawn from the passage.

*The assessment has been researched and verified in controlled studies and is now available to districts for a limited, trial use to gather feedback.
CBMcomp
Universal Screening and Progress Monitoring | Grades 1–8 | Teacher-Administered | Curriculum-Based Measure | Time Required: 5–10 min | Lab Status*
CBMcomp is a supplemental assessment to CBMreading that measures oral reading fluency and students’ ability to recall information from passages of connected text in two parts:
CBMcomp Recall provides standardized prompts to the student to recall the story. The teacher marks each of approximately 17 important details as the student recalls them to define the thoroughness of the recall.
CBMcomp Questions provides directions and 10 standardized, passage-specific comprehension questions with answers. Comprehension accuracy is reported on a scale from 0 to 100% and takes approximately one minute to administer and score online.
