At the end of the year (EOY), 82% of students were correctly classified on the ISIP Reading with respect to Smarter Balanced. ISIP Reading accurately predicted meeting ELA proficiency on Smarter Balanced about 80% of the time at MOY and 85% of the time at EOY.
Linking NWEA MAP Reading to ISIP Reading (2022)
This study provided the proficiency projection and classification accuracy of ISIP Reading on the NWEA MAP Reading assessments for kindergarten through eighth grade. Strong correlations indicated positive relationships between the ISIP Reading and the NWEA MAP Reading assessments. At the middle of the year (MOY), 79% of students were correctly classified on ISIP Reading with respect to NWEA MAP. At the end of the year (EOY), 76% of students were correctly classified on the ISIP Reading with respect to the NWEA MAP. ISIP Reading accurately predicted meeting ELA proficiency on the NWEA MAP about 80% of the time both at MOY and EOY.
Linking ISIP Reading to the New Jersey Student Learning Assessment (NJSLA) (2022)
This study provided the proficiency projection and classification accuracy of ISIP Reading on the NJSLA-ELA for third through eighth grade. Strong correlations indicated positive relationships between the ISIP Reading and the NJSLA-ELA. Between 62% and 81% of students were correctly classified on ISIP Reading with respect to the performance level 4 on the NJSLA-ELA (Met Expectations or higher), whereas 69-77% of students who were not classified at Met Expectations or above did in fact not reach level 4 or above. Students in this sample had to attain high scores on ISIP to attain a medium likelihood of achieving level 4 or level 5 (Exceeded Expectations) on NJSLA-ELA. Cut points at the 30th to 35th percentiles showed good classification accuracy for predicting students who would pass the state assessment.
Predicting TELPAS Overall Category Rankings Using the ISIP Reading (2022)
ISIP Reading is linked to the Texas Evaluation of Language Proficiency System (TELPAS). Student percentile ranks on the winter administration predict the likelihood of achieving the Advanced or Advanced High category on the TELPAS. Students in grade 2 need to be at the 95th percentile or higher on ISIP Reading to have high odds of reaching Advanced High on the TELPAS. Students in grade 3 need to be at the 76th percentile or higher, students in grade 4 need to be at the 71st percentile, and students in grade 5 need to be at the 56th percentile or higher to have high odds of reaching Advanced High on the TELPAS.
From Disruption to Recovery (2022)
This study investigates the effects of the COVID-19 pandemic on students’ achievement in reading and math across the US. Data were collected from the 2018- 2019, 2019-2020, and 2020-2021 school years. Istation’s Indicators of Progress (ISIP™) Reading and ISIP Math assessments were used. Results from a piecewise growth model show that students performed well before the COVID-19 pandemic. Students experienced a summer learning loss in both reading and math depending on grade level before the pandemic. All students experienced a combination of summer learning loss and COVID-19 learning disruption during the pandemic. Students’ academic performance was lower during the pandemic.
Using computer-adaptive curriculum to increase English literacy in emerging bilingual students (2022)
Istation partnered with a large urban school district to study the impact of the reading curriculum in English and Spanish on bilingual students’ English language proficiency, as measured by the Texas Evaluation of Language Proficiency System (TELPAS). A logistic regression mixed effects model found that emerging bilingual students in grades 2 and 3 had better odds of improving a level on the TELPAS if they used the Istation Spanish curriculum at the recommended levels, and used less of the English curriculum. Students who were in the Advanced category on TELPAS the previous year had better odds of reaching Advanced High if they used the English curriculum more than they used the Spanish curriculum.
The efficacy of a computer-adaptive reading program on grade 5 students’ reading achievement scores (2022)
Designed to qualify for ESSA Tier 2 evidence, this study used propensity score matching, a quasi experimental design, to evaluate the impact of using Istation curriculum with fifth grade students. Students who used the curriculum had statistically significant higher gains than students in the control group on their overall reading, vocabulary, and reading comprehension scores.
The influence of a computer-adaptive reading program on fourth-grade students’ reading achievement scores (2021)
This study investigated how incorporating technology into the classroom for reading instruction helped students’ reading growth. Fourth grade students who used the Istation curriculum for the recommended weekly minutes demonstrated greater learning gains than students who did not use the curriculum.
Comparability of ISIP™ Reading Scores Across Alternate Backgrounds (2021)
This research evaluates whether student performance is comparable on the ISIP ER when the background changes color while keeping the content consistent. Results show that after controlling for prior achievement and ability level, having a new background slightly increased student performance. Effects varied by grade and subtest; however, all effect sizes were small. The most likely explanation is a novelty effect as the students were exposed to a background that was different than what they had been used to seeing on their monthly assessment.

Predicting Second-Grade Students’ Yearly Standardized Reading Achievement Using the ISIP ER (2020)
- A free copy is available by searching the Education Resources Information Center (ERIC) and Academic Search Complete databases, available at most public or university libraries.
The present study investigated the predictability of a computer-adaptive, curriculum-based reading assessment for measuring second-grade students' overall and comprehension reading achievement on a standardized reading achievement test. Specifically, second-grade student scores (N = 428) of the Istation's Indicators of Progress for Early Reading (ISIP-ER) and the Standardized Test for the Assessment of Reading (STAR Reading) in one state were examined. Linear regression analysis was conducted to determine the predictability between the ISIP-ER and STAR Reading scores, identifying that both the ISIP-ER overall reading and comprehension scores in December predicted the standardized reading scores in Spring (May). Confidence intervals were estimated to identify the ISIP-ER cut scores that predict STAR Reading scores for all achievement levels. Overall, ISIP-ER shows promise as a universal screening tool for second-grade student yearly reading skills.
Computer-Adaptive Reading to Improve Reading Achievement Among Third-Grade Students At-Risk for Reading Failure (2020)
An essential goal of educational instruction is to ensure that all students become competent readers. To support students in becoming qualified readers, teachers need to identify struggling students and implement adequate curriculum programs. This study examined the effects of a computer-adaptive reading program on third-grade students’ reading achievement, accounting for their achievement level, their usage of computer-adaptive reading program, gender, and free and reduced lunch eligibility. Results indicated that students in the lowest academic level and in the greatest need of intensive reading instruction evidenced greater gains than those above the 20th percentile, exceeding normed expectations. On average, the achievement gap for students in the lowest academic level remained evident. The study provided evidence regarding the benefits of computer-adaptive environments to narrow achievement inequalities and increase opportunities for students who are at the greatest risk of reading failure.

Predictability "bands" were further computed by using the confidence interval (CI) approach to identify the ISIP cut scores that predict five performance levels. Results of the regression models show that the ISIP Reading measures are predictive of Ohio AIR ELA, and ISIP Math measures are predictive of the Ohio AIR Math assessment. The ISIP Overall Reading and Math ability cut scores to predict Ohio AIR performance levels Limited, Basic, Proficient, Accelerated, and Advanced are reported.
Kindergarten through Grade 5 Report
English Language Learners (ELLs) constitute 9.5% of the student population in the US, and of these students 77.1% are Spanish speakers (NCES, 2017). Istation Lectura Temprana (ISIP Español LT) and Lectura Avanzada (ISIP Español LA) assessments for kindergarten through grade 5 screen for Spanish language skills and help teachers identify whether students are on track for reaching Spanish language goals. This research examines the validity evidence between the ISIP Español LT and ISIP Español LA assessments and other assessment instruments including the Fast Bridge Spanish, Aprenda 3, PARCC, and Texas STAAR exams. The sample consisted of students in the southwestern United States who speak Spanish. Correlations were moderate to strong across all grades and assessments, and classification accuracy increased as the school year progressed.
Prekindergarten Report
Results from assessments such as the Istation Lectura Temprana (ISIP Español LT) can help educators identify whether students in prekindergarten are on track for reaching Spanish-language goals. There are very few universal Spanish screeners available for these young students, and this research evaluates the ISIP Español LT assessment. Data were collected in two school districts in Texas during the 2017-2018 school year. Concurrent validity and sensitivity analysis was conducted using the Fast Bridge Early Reading Spanish and the Spanish Individual Growth and Development Indicators (IGDIs Español) in the fall, winter, and spring semesters.
