TEA Data Presentation - Group 1

  1. 1. Under the Influence November 20, 2014 Dallas Independent School District By: ChinLin Pan, Hymi Ashenafi, Taylor Turner and Keneshia Colwell
  2. 2. Dallas ISD – Dallas ISD is the second-largest public school district in Texas and the 14th largest district in the nation. – The district has 220 schools with 157,000 students, Pre K-12. – The district also employs nearly 20,000 professionals.
  3. 3. Data items we looked at: • Teacher turnover rate: Percentage of teachers who left the district. Various reasons can contribute to the reason of departure, including demographics or salary. • Teacher-student ratio: This is the number of students per teacher. • High school graduation rates.
  4. 4. • We also looked at several neighboring districts of Dallas ISD, namely Plano, Garland and Richardson. • We looked at the turnover rate, teacher-student ratio and graduation rate of all four districts.
  5. 5. Map of districts we researched:
  6. 6. Here is a general map of Dallas and the bigger cities around it to give an idea of where Dallas is:
  7. 7. Steps taken to reach data source: • TEA Website • Clicked “Reports & Data” • Clicked “Academic Excellence Indicator” • Clicked the year “2011” • Clicked “districts”
  8. 8. Ed Timms Datasheet
  9. 9. Information on upcoming graphs: • We looked at turnover rates versus graduation rates and found a correlation. • The less of a teacher turnover rate, the more students graduate. • In each graph, we’ve compared all the listings side by side by district. • The Y axis is the percentage for each X category. Since graduation rates skewed the data, we divided the actual graduation rate by 10 to fit the graph visually. – Dallas: 77.3/%10= 7.73 – Garland: 87.7%/10= 8.77 – Richardson: 91.1%/10= 9.1 – Plano: 93.4%/10= 9.34 – These numbers are displayed in each graph as the smallest number listed above.

(93.4%) • Richardson ISD has the second lowest teacher/student ratio (15.3) and the second highest graduation rate. (91.1%) • Dallas ISD has second highest teacher/student ratio (15.3) and the lowest graduation rate.
