# Shock Exposure Index (SEI)

The **Shock Exposure Index (SEI)** measures the overall **degree of shock and/or stressor exposure** to context-specific shocks at the household level. By gathering data on a range of covariate and idiosyncratic shocks, it can support programme monitoring and learning by providing information on the **frequency and severity of shocks** experienced in-context especially for resilience programmes.

The SEI is adapted from the TANGO Method designed by USAID (2018) and is a subjective approach to measuring the impact of shocks and/or stressors collected through household surveys.

There are currently two-forms of the SEI available on the RAM IM Ecosystem: A **long-form version** based on the original TANGO Method (covering 18 shocks) and a **short-form version** endorsed by WFP (covering 6 context-specific shocks).

Please find below the resources that will help you in collecting, analysing and interpreting the SEI indicator:

The [**SEI**](https://docs.wfp.org/api/documents/WFP-0000150657/download/) methodological note containing all relevant information on the design, collection and analysis of the indicator.

The long form and short form SEI are available on [**WFP Survey Designer**](https://surveydesigner.vam.wfp.org/), to help simplify the authoring of forms in Excel. The XLS forms can be converted to ODK forms, a popular open-source data collection software, that allows you to author a form with complex functionality in a consistent way, across a number of web and mobile data collection platforms.

The SPSS code to calculate the SEI is available on [**GitHub**](https://github.com/WFP-VAM/RAMResourcesScripts) – which hosts scripts in R, STATA and SPSS - that are already created for you.
