Item Analysis Program: Iteman 4.5
Assessment Systems Corp. has released version 4.5 of the popular program Iteman, an item analysis program that I have used for since being director of testing and accountability.
The program now self-generates a report. For my testing of the program on 100 subjects on an 18 item Math 1 test using the demo version created a 30-page report. The report provides item-level analysis including p and discrimination values. The quartile plot created by the program provides insight into responses not available in other easy-to-use programs. The 46-page User Manual is very complete and provides file setup and some interpretive information.

For this brief report, the impact of being out of school and doing home-based learning for grade 3 students was examined in a rural school district. The sample size is approximately 300 students.
- I-Ready beginning of the year (BOY) reading test overall percentile score converted to an NCE (normal curve equivalent) score.
- Beginning of Grade 3 (BOG) ELA test percentile rank score converted to NCE score.
- Difference scores between each student’s I-Ready BOY NCE and the corresponding BOG NCE score. By using intra-individual score differences, differences in overall average score from the two different cohort groups were not a confounding factor for this analysis.
- BOG percent proficient was computed using counts of level 3-5 and dividing it by the total number of scores. This was computed for each school.
For the fall 2019 and the 2020 (current year) the BOG scores were collected and matched into a single table with the previous year I-Ready BOY data score.
- The joined table included columns for the year, school, SID, I-Ready tier, NCE BOG, and NCE I-Ready scores.
- A difference score was computed for each student by subtracting the BOY I-Ready NCE score from the BOG NCE score. For example:
2020 BOG NCE = 50 and the BOY I-Ready NCE score = 45 difference = +5
- For each school the average of the differences was computed.
- NCE score differences were disaggregated by school and by reading tier (Tier 1, Tier 2, and At-risk for Tier 3).
- The average I-Ready to BOG NCE difference for the 2019-20 school year for the district was 6.5 with a range of 1.0 to 9.7.
- The average I-Ready to BOG NCE difference for the 2020-21 school year for the district was -19.8 with a range of -17.8 to -24.2.
- Differences by Tier for the two different school years were as follows:
- 2019 Tier 1 5 Tier 2 6.7 At-Risk for Tier 3 10.1
- 2020 Tier 1 -26.8 Tier 2 -20.7 At-Risk for Tier 3 -9.9
- The 2019 BOG district proficiency was 24.1% and this is a consistent score for the last three years. The 2020 district proficiency was 11.5%.
The impact of being out of school for the spring of 2020 due to the pandemic is measurable for grade 3 students using the methodology described above. Furthermore, the results suggest that there is a negative impact on reading performance for the student in this district, and the impact cuts across all reading tier levels.
Present this data to the schools and make a school roster of students for each school so that the school leaders and teachers can identify the students who experienced the greatest negative impact so that interventions can be provided.
Use the I-Ready diagnostic data to determine if there is a pattern of weak areas across the most negatively impacted students. For each student determine specific areas had the greatest negative impact and provide targeted individual intervention.
While growth for grade 3 students can be determined by comparing BOG to EOG NCE scores, Percent proficient for grade 3 is quite likely to be lower than the 2018 EOY percent proficient. This is likely to be the case for ELA for grades 3-8. Accountability using the current targets will be problematic.
