EARLY WARNING SYSTEMS (EWS)

Early warning systems rely on readily available data housed at the school to:• Predict which students are at risk for dropping out of high

school

• Target resources to support off-track students while they are still in school, before they drop out

• Examine patterns and identify school climate issues

Research from several U.S. school districts provides a strong foundation for defining early warning signs that students might drop out, but local adaptation is key.

Early warning indicators are used only for prediction—they do not cause students to drop out. Rather, they should

be treated as symptoms of the dropout process that is in progress.

HOW DO YOU USE DATA IN YOUR SCHOOL?• How do you use data to inform decisions in your school? Do

you use a framework?• Does your process overlap with any early warning indicators

data?• What are similarities to those frameworks?• What are some of the differences to those frameworks? • How do you ensure student supports match student needs?

STEP ONE: ESTABLISH ROLES AND RESPONSIBILITIES• EWS teams need to include individuals who have:

o Authority to make decisionso Knowledge of diverse studentso Expertise to manage and analyze data

• EWS team are required to:o Meet regularly o Communicate EWS risk or dropout prevention issues to

groups/individuals outside of the teamo Solicit feedback from stakeholders (leaders, staff, students, parents)o Monitor students’ progress

STEP TWO: USE AN EWS TOOL• Important EWS tool (middle grades and high school)

considerations: o Data must be regularly entered throughout the school yearo At least one individual should be responsible for ensuring the

EWS tool is loaded with the latest datao EWS Team members must be trained to understand the use of

the indicators within the toolo Reports must be used and accessible in order to make

decisions about students’ needso Student progress in interventions must be monitored

STEP THREE: REVIEW EWS DATA• EWS indicators are reviewed and monitored to identify students at risk for

dropping out and to understand patterns in student engagement and academic performance

• Questions to ask about EWS data:o Student-level patterns: What do your data tell you about individual

students who are at-risk?o School-level patterns: What do your data tell you about how the school

is doing?• Are students who were flagged from the beginning remaining “off-track”

through the year?• Are students who were flagged at one reporting period back “on-track” at

the next?

WHOLE GROUP DISCUSSION TIME: KEY QUESTIONS FOR STEPS 1-3• Step 1: Who needs to be

represented on the EWS team and what types of knowledge do team members need to have?• Step 2: How frequently will

the EWS data be monitored? • Step 3: What do you need

to have in place so you are confident that your data are accurate?

STEP FOUR: INTERPRET EWS DATA• The EWS team must look BEYOND the indicators

o Indicators are just observable symptoms, not root causes

o Root causes emerge through examining additional data from a variety of sources beyond the EWS indicators

• Looking at data beyond EWS Indicators can:

o Help identify individual and common needs among groups of students

o Raise new questions and increase understanding of why students’ fall off-track for graduation

JECT

Practice in Motion!

STEP FOUR, CONTINUED• Understanding characteristics of students at-risk of dropout is

important because:

o Decisions to persist or drop out are affected by multiple contextual factors - family, school, neighborhood, peers

o Personal and school factors contribute to success or failure during the freshman year

o EWS indicators, such as attendance and course performance problems are distinct indicators of risk, but are highly interrelated, and both can signal disengagement

o Student background characteristics are less important in explaining failures than behaviors in the middle grades and in high school

STEP FIVE: ASSIGN AND PROVIDE INTERVENTIONS• The EWIMS team matches individual students to specific

interventions after having gathered information about:

o Potential root causes for individual students who are flagged as at risk

o The available academic and behavioral support and dropout prevention programs in the school, district, and community

• A tiered approach can be used to match students to interventions based on their individual needs

STEP SIX: MONITOR STUDENTS AND INTERVENTIONS• The EWS team monitors students who are participating in interventions to:

o Make necessary changes by identifying students’ whose needs are not being met, and/or those students who may no longer be struggling

o Identify new interventions that will to meet students’ needso Use data to monitor the effectiveness of interventions offered

• Increase knowledge about the general effectiveness of interventions• Improve the matching of students to interventions

o Communicate with appropriate stakeholders and solicit their involvement in the process (e.g., feeder schools, next grade level)
