2012 English Language Arts MCAS data by Population Group/Performance Level

Illustrating MCAS results in Mekko Graphics charts

I had the opportunity this week to demonstrate how Mekko Graphics could meet the data analysis needs of today’s educators, who find themselves deluged with information from skills assessments, standardized tests, and other sources. In preparation, I created several charts to highlight Mekko Graphics’ ability to illustrate Massachusetts Comprehensive Assessment System (MCAS) test results. Some of the resulting charts are included below along with the underlying source table.

2012 English Language Arts MCAS data by Population Group/Performance Level

The Marimekko charts above graphically answer the question “how are we doing by population group vs. the district?” They demonstrate that:

  • On average, the students in each of the school’s population groups underperformed their district counterparts in 2012.
  • The underperformance was slightly more acute amongst the school’s smaller population groups.

The Stacked Bar chart above uses comparison lines to highlight the following trends:

  • The percentage of students in the Warning/Fail performance level is trending in the right direction, lower.
  • The percentage of students who scored Proficient is also trending positively, higher.
  • Intervention may be required to reverse the 2% loss at the Advanced performance level.
Traditional tabular MCAS data

When it comes to MCAS results, Mekko Graphics charts illustrate the data more effectively than the traditional tabular format. As we continue our work in the educational space, we’ll publish additional examples that demonstrate Mekko Graphics’ ability to augment instructional technology products and transform the school improvement process through insightful analytical charting.
