Individual Growth Profile Tutorial

The Growth Profile consists of a main graph and a subgraph. The main graph shows your selected student’s areas of relative strength and weakness. Areas of high and low growth may be highlighted. The subgraph plots growth trends for subtests you select from the main graph. Reading and Math Total trends are shown by default. Growth projections and GE/SS labels may be added to the subgraph.

Click on a feature for more information:

GE/SS Toggle Switch

Use this button to toggle between Grade Equivalents and Standard Scores. eITP will default to the SS scale for all individual growth profiles.

Plotting Trends with Subtest Tabs

The Iowa Tests are listed across the top of the growth profile chart. We will refer to these as "Subtests." All subtests can be selected for trend display on the subgraph by simply clicking on the subtest name. A maximum of four subtests may be simultaneously selected for trend display. This main graph is similar to the growth profile charts that many Iowa students, parents, teachers, and administrators receive.

Growth Data – Grade Equivalents and Standard Scores Over Time

Depending on the GE/SS toggle switch, the main graph shows the National Standard Score or the National Grade Equivalent (NGE) for any available test or composite. Each colored line is associated with a particular school year in the past. In the example, the student’s results are available each year from Grade 3 (in school year '06-'07) to Grade 7 (in school year '10-'11). Peaks and valleys in the profile represent areas of relative academic strength and weakness. Vertical distance between the lines represents growth on a particular subtest. If there are breaks in a single colored line, these gaps refer to subtests with no data available or data that did not meet the minimum requirements for growth profile displays.

Highlighting Areas of High or Low Growth

You may use this feature to highlight areas of particularly high or low growth. The default is set to highlight growth that is greater than 1 GE per year under the GE view or 12 SS points under the SS view. Note that 12 SS points is an arbitrary number that does not necessarily correspond to 1 GE. Click the "View" button to highlight these areas on the main graph. Filled "Growth Bars" will appear wherever the criterion you specify is met. Click "Reset" to remove the Growth Bars. The 1 GE or 12 SS default value can be changed by clicking the cell and entering a new value. Use the drop-down menu to highlight and click "less than" to view areas of particularly low growth.

The Subgraph Legend and Axes

The subgraph plots selected subtest trends from the main graph. These subtests are shown in their associated color in the subgraph legend. Subtest trends can be added or removed by clicking the appropriate subtest name in the main graph. The horizontal axis shows the time of testing (F)all, (M)idyear, or (S)pring. If your district changed its primary time of testing, the trends are plotted on the appropriate time in the school year.

Growth Trends and Growth Projections

Subgraph growth trends show the change in academic proficiency for the selected student. Moving the mouse over a particular data point reveals a dotted growth projection. Clicking the point freezes this growth projection on the subgraph. This growth projection is neither a growth expectation nor a growth standard. If GEs are selected, this projection shows the National Grade Equivalent (NGE) of the average score that maintains the same National Percentile Rank (NPR) over time. If SSs are selected, this projection represents the Standard Score gain needed to maintain National Percentile Rank. Average growth at projected levels may be thought of as a benchmark for maintaining relative status with respect to the national distribution over time.

Show/Hide GEs/SSs

Clicking the "Show GEs" or "Show SSs" button will attach labels to each subtest trend with the associated Grade Equivalent or Standard Score. These labels can be moved by clicking them and dragging them to different locations. This may help to unclutter the side graph when more than two growth trends are simultaneously plotted. Clicking the button again will hide the GE or SS labels.
