Determining the Continuous Progress Indicator
Use of the CPI in reviewing the progress of schools is based on an expectation that the percentage of students reaching the Proficient level or above in the WKCE subject areas will continue to increase until all, or nearly all, students have attained that goal. The CPI is intended to serve as the primary basis for reviewing the effectiveness of a school in helping each successive group of students in grade 4, 8, or 10 reach the Proficient level or above. There is no prescribed time frame for attaining the goal.
The CPI is different from previously proposed measures of progress in that this Indicator recognizes decreases in the percentages of students in the "Not Tested" and "Minimal Performance" categories in addition to increases in the percentages at or above the Proficient level. This change makes the CPI more sensitive to improvements in all schools, thus emphasizing the continuous progress notion for both low- and high-scoring schools. An example of how to calculate the CPI for 1998-99 is provided in Table 1.

CPI for 1998-99: 6
Note that Improvement is positive if there is a reduction in the % Not Tested or Minimal and/or an increase in the % Proficient or Above.
Another difference between the CPI and other proposed measures is that four years rather than two years of proficiency scores would be used each year in measuring progress. Since 1997-98 was the first year of proficiency reporting, sufficient data to implement this feature of the CPI will not be available until after 2000-01 testing.
The use of four years rather than two years of scores to calculate the CPI tends to reduce the effect of error on the Indicator. This is particularly important in measuring progress of very small schools. Using four years of data would also address concerns about variation in the characteristics of successive groups of students at the given grade level.
For 1999-2000, three years of proficiency scores would be used to calculate the CPI because only three years would be available. Results for 1999-2000 would be compared to the average of the results for 1997-98 and 1998-99.
Beginning with test results for 2000-01, the CPI would be calculated based on the four most recent years of test scores. The average of the two most recent years would be compared to the average of the two years preceding that period. For 2000-01, this means that the average of 1997-98 and 1998-99 would be compared to the average of 1999-2000 and 2000-01. See Table 2.

CPI for 2000-01: 17
In the school described in Table 2, if only two years of proficiency data were used, then the CPI for 2000-01 would be 7 rather than 17. To understand this calculation, look at the column "% not tested or minimal." From 1999-2000 (28%) to the 2000-2001 (21%) school year there was a 7% improvement.
If the CPI is as large or larger than the Required CPI below, then the school has met the improvement requirement for that subject and grade. Schools at lower achievement levels would be expected to make more progress than other schools. For 1998-1999, the Baseline % At or Above Proficient would be the % Proficient or Above for 1997-98. For 1999-2000 and 2000-01, the Baseline % At or Above Proficient would be the average of 1997-98 and 1998-99. For 2001-02, the Baseline % At or Above Proficient would be the average of 1998-99 and 1999-2000 and so on. See Table 3.

Stay above this level |
In the school described by Table 1, the Baseline % At or Above Proficient was 54% in science. Based on Table 3, the Required CPI is 2. If the 1998-99 CPI for the school is 6, as shown, then the school exceeded the Required CPI in science.
In the school described by Table 2, the Baseline % At or Above Proficient was 38% in mathematics. This is the average percent Proficient or Above for 1997-98 and 1998-99. Based on Table 3, the Required CPI is 3. The 2000-01 CPI for the school is 17, as shown, then the school exceeded the Required CPI in mathematics. For 2001-02, the Baseline % At or Above Proficient would be the average percent Proficient or Above for 1998-99 and 1999-2000, i.e., 43%.
No specific amount of progress would be prescribed for schools that exceed 80% at or above the Proficient level as long as 80% of the students score at or above the Proficient level. Continued progress of these schools, to the goal of all or nearly all students attaining the Proficient level, will be considered as DPI clarifies its policy regarding the identification of Distinguished Schools.
Integrating the Use of 90% of the State Average with the CPI
Through school year 2000-01, annual review of school performance will be based on the following:
- Percent scoring at the Proficient level or above in each subject is at least 90% of the 1997-98 statewide percent in that subject. This is called the "90% rule."
OR
- Meet the Required CPI for each subject

These criteria would apply to reviews for reading, mathematics, science, and social studies. The criteria for language arts will be one year behind due to changes in the way language arts will be considered for accountability purposes beginning with the results of 1998-99 testing. The 90% rule for language arts will be based on 1998-99 test results.
Beginning with test results for school year 2001-02, the use of the 90% rule would be discontinued in all subject areas. The CPI would be fully implemented; the previous four years of data would be used for annual review purposes.
Note that only scores of students enrolled for the full academic year prior to testing are considered. With February testing this means three semesters or more at the same school. As has been true beginning with 1997-98 test results, schools would not be identified for improvement in a subject unless the Required Achievement Level or CPI indicated in Table 4 is below the necessary level for two consecutive years.
