Capti AssessFrequently Asked Questions

General Questions

  • What reading skills does ETS ReadBasix™ test?

    The ETS ReadBasix™ assessment is composed of six subtests that assess reading skills in:

    1. Word Recognition & Decoding
    2. Vocabulary
    3. Morphology
    4. Sentence Processing
    5. Reading Efficiency
    6. Reading Comprehension
    Each subtest assesses a specific component of reading that may be affecting a student's reading success. The five foundational reading skills are not measured by other assessments that focus only on reading comprehension. Capti Assess allows educators to evaluate foundational skills independently in 5-10 minutes each. Learn more about subtests.

  • Is the ETS ReadBasix™ assessment the same as RISE / SARA?

    Yes. ETS ReadBasix™ is the modern version of RISE / SARA developed on top of the Capti Assess platform. Capti Assess provides an easy to use user interface, insightful reports, actionable recommendations, instructional grouping, and student management tools, while ReadBasix is the reading assessment.

  • What is RISE / SARA, and how is it related to ReadBasix?

    RISE / SARA are the original names of ETS ReadBasix. RISE / SARA was shown to predict state reading scores and performance on other standardized measures of reading comprehension. This research has been used to identify students who are likely below proficient on a state test. For more details, refer to the SARA/RISE technical report.

  • Who developed the ETS ReadBasix™ assessment, what is the science behind it?

    ETS ReadBasix™ was developed by ETS (Educational Testing Service), a world leader in assessment development. Learn more about the science behind it.

  • How does ETS ReadBasix™ align with the Science of Reading?

    ETS ReadBasix™ was created by researchers while working on the Reading for Understanding(RfU) Initiative by the Institute of Education Sciences (U.S. Department of Education). The latest Science of Reading includes research from a variety of interdisciplinary fields including Cognitive Psychology, Communication Sciences, Developmental Psychology, Education, Special Education, Implementation Science, Linguistics, Neuroscience, and School Psychology. A team of experts led by Dr. John Sabatini, a world-renowned reading researcher, developed the assessment based on the Science of Reading principles. This assessment measures key foundational reading skills derived from the Science of Reading literature, which allows educators to effectively identify areas where learners struggle. Since teachers can pinpoint the areas of need, they help students overcome reading deficiencies, and make the U.S. education system better prepared for the 21st century.

  • Does the ETS ReadBasix™ assessment align with the Common Core State Standards (CCSS)?

    ReadBasix aligns with the CCSS for foundational reading skills, language standards, and the college and career readiness anchor standards for reading. The foundational reading skills standards cover constructs related to ReadBasix including decoding, word recognition, fluency, and morphology. ReadBasix augments the standards by measuring the five foundational skills beyond grade 5 (where the foundational reading skills in the CCSS end). Failure to measure foundational skills beyond grade 5 may limit the detection of key sources of reading issues. ReadBasix can assist educators in determining sources of reading difficulties with students in grades 6-12 where foundational reading skill standards are assumed to be fully developed, and therefore not addressed.

    Language standards cover constructs related to vocabulary and sentence processing, which are focused on in the CCSS from grades 3-12. ReadBasix specifically measures the language standards aligned with choosing words and phrases for effect (i.e., L.3.3a., L.4.3a.) and pronoun use (i.e., L.6.1c., L.6.1d.).

    The college and career readiness anchor standards for reading cover constructs related to ReadBasix's comprehension subtest. Specifically, the reading comprehension subtest measures CCSS anchor standards 1, 2, and 4 related to reading closely, determining central ideas, and interpreting words and phrases used within a text.

    Given that the assessment is aligned with standards, it does show progress with the skills addressed in the standards. Each subtest uniquely demonstrates progress on various standards. The list below shows an overview of the connection between each subtest and its aligned standards.

    1. Word Recognition & Decoding - CCSS Reading Standards, Foundational Skills, Phonics and Word Recognition
    2. Vocabulary - CCSS Language Standards, Vocabulary Use and Acquisition
    3. Morphology - CCSS Reading Standards, Foundational Skills, Phonics and Word Recognition
    4. Sentence Processing - CCSS Language Standards, Knowledge of Language
    5. Reading Efficiency - CCSS Reading Standards, Foundational Skills, Fluency
    6. Reading Comprehension - CCSS Reading Anchor Standards 1, 2, and 4
  • At which grade levels can students take the ETS ReadBasix™ assessment?

    Students in grades 3-12 can complete the ETS ReadBasix™ assessment. ETS ReadBasix™ does not have data on students below grade 3. ETS ReadBasix™ is not recommended for students who do not have beginner decoding skills required to complete, at least, the Word Recognition and Decoding subtest.

  • Does the ETS ReadBasix™ assessment have different difficulty levels?

    ETS ReadBasix™ has three levels of difficulty (low, medium, high) that roughly align with elementary, middle, and high school level. ETS ReadBasix™ automatically personalizes the difficulty of each subtest for every student based on their previous performance.

  • Does the ETS ReadBasix™ assessment work for students learning English as an additional language?

    ETS ReadBasix™ works well for identifying strengths and weaknesses in foundational reading skills for students learning English as an additional language.

  • Is the ETS ReadBasix™ assessment available in Spanish or other languages?

    No, the ETS ReadBasix™ assessment is only available in English. Be the first to find out when ETS ReadBasix becomes available in Spanish

  • Are there intervention exercises associated or integrated with the ETS ReadBasix™ assessment?

    SERP Institute’s STARI — an amazing reading-based intervention for middle schools — has been aligned and validated with ReadBasix.

    Currently, there are no interventions directly integrated with the ETS ReadBasix™ assessment; however, Capti is developing Capti Advance, a cutting-edge intervention that will tailor questions to students based on their ETS ReadBasix™ scores. Capti Advance will allow teachers to import any content to create intervention exercises. Be the first to find out when an intervention gets integrated.

Scoring and Reports

  • What are the ETS ReadBasix™ assessment scaled scores based on?

    The scaled score is a representation of the total number of correct answers a student has provided that has been converted onto a consistent and standardized scale. Each subtest provides a score between 190 to 310. There are four bands of scores: strong performance (265-310), high average performance (250-264), low average performance (236-249), and weak performance (190-235).

  • How are the ETS ReadBasix™ assessment scores computed?

    Scores are computed based on a statistical algorithm grounded in state-of-the-art research on reading science and item response theory. The algorithm considers the pattern of correctly answered items and various item statistics. This approach places all scores across all grades on a common scale such that they can be directly compared. The percentiles are based on a weighted national sample of students and the associated score distributions at each grade level.

  • How do the ETS ReadBasix™ assessment scores scale across grade levels?

    The ETS ReadBasix™ assessment scores are vertically scaled to allow for seamless cross-grade score comparisons. Additionally, the scores are nationally-normed to provide a grade-level percentile and students’ grade equivalent score for each skill.

  • Does the ETS ReadBasix™ assessment provide a Lexile level?

    Yes, a Lexile score is computed based on the results from 3 ReadBasix subtests: sentence processing, efficiency, and reading comprehension.

  • Can I customize the RTI Percentile settings to better represent my class/school?

    By default, students are recommended RTI Tier 1 if their score is above the 25th percentile; RTI Tier 2 is recommended if the score is above the 10th percentile but below Tier 1; and RTI Tier 3 is recommended in all other cases. However, Organization account members with the Administrator role can customize the thresholds for the RTI tiers to better represent the class/school.

  • How do I use the data provided by the ETS ReadBasix™ assessment?

    The ETS ReadBasix™ assessment provides data for each subtest students complete. The results indicate strengths and weaknesses in each foundational skill. Class-wide data illuminates the trends across a group of students, which allows for small groups to be formed for targeted reading interventions based on the identification of weaker skills.

    Additionally, response to intervention (RTI) tier recommendations are provided to help with the instructional decision making process. For instance, when a student scores above the 25th percentile, the recommendation is for the student to receive tier 1 instruction, whereas when a student scores below the 10th percentile on a reading skill, the recommendation is for the student to receive tier 3 support.

    Data can also be used to measure progress students make over the course of the school year by having students complete all subtests three times a year. Data from the assessment can help determine whether or not the student requires further evaluation for reading difficulties.

  • How is personally identifiable student data safeguarded?

    Capti has strict safeguards in place to protect the confidentiality of personally identifiable student data. Capti is compliant with FERPA, COPPA, and NY2D Law. At Capti, all assessment data is stored on AWS servers. AWS encrypts all Capti data volumes with a data key using the industry-standard AES-256 algorithm. It should be noted that personally identifiable student data is not required to use and administer Capti Assess with ETS ReadBasix, students can be rostered anonymously.

Implementation, Administration, and PD

  • How do you implement Capti Assess?

    For implementation, please see an Implementation Plan Example.

  • How long does the ETS ReadBasix™ assessment take to complete?

    The ETS ReadBasix™ assessment can be taken one subtest at a time, all subtests at once, or in any combination. Each subtest, except for the basic reading comprehension, takes about 7-9 minutes to complete, counting the time to read the instructions and complete a few practice questions. The basic reading comprehension subtest takes 20-30 minutes on average. All subtests together take approximately 45-75 minutes to complete, depending on the student. However, focusing on the specific skills of interest, can significantly reduce the assessment time.

  • How often should you administer the ETS ReadBasix™ assessment?

    It is recommended that students complete the ETS ReadBasix™ assessment at the beginning of the year for screening purposes. Then, each subtest should be administered two more times (a total of three times) during the year to measure progress. Additionally, you can administer specific subtests every six to eight weeks to measure progress from targeted interventions.

  • What devices can you use to take/administer the ETS ReadBasix™ assessment?

    ETS ReadBasix™ is a universally accessible assessment. All you need is access to the Internet and a browser (e.g., Edge, Safari, Chrome, Firefox) to take the assessment. ETS ReadBasix™ can be taken on any device that has internet access, such as a PC, Mac, Chromebook, or tablet.
