Transparency International (TI) is the global civil society organisation leading the fight against corruption. Through more than 100 chapters worldwide and an international secretariat in Berlin, Germany, TI raises awareness of the damaging effects of corruption and works with partners in government, business and civil society to develop and implement effective measures to tackle it.

As an evidence-based advocacy anti-corruption organisation, measuring corruption is at the heart of TI’s work. On the global level TI does this through the Corruption Perceptions Index (CPI) and the Global Corruption Barometer (GCB). The CPI is one of the most well-known corruption measurement tools. It has been published annually since 1995 and the most recent edition of the CPI was launched in January 2019 and covered 180 countries and territories. It is widely used by governments, businesses and other stakeholders worldwide to assess the level of public sector corruption in a given country.

The GCB is the largest worldwide public opinion survey on views and experiences of corruption. As a poll of the general public, it captures both people’s experiences with bribery across different institutions and also their views and perception of both corruption and the effectiveness of the government in fighting corruption. The last GCB round covered 119 countries and territories around the globe and was based on interviews with more than 160,000 adults.

In order to ensure the quality and reliability of the data, the CPI is computed independently by two in-house researchers from the TI secretariat as well as two external co-calculators. The results obtained independently from all four researchers are then compared to ensure that they match. For the Global Corruption Barometer, survey data files are validated by external consultants/ organisations, and all publications are externally checked by consultants against the original data set to verify the accuracy of the results.

Transparency International Secretariat (TI-S) in Berlin is seeking external contributors to join a 2-year framework agreement to support the global tools by providing ad-hoc data analysis; figure checking data-driven publications; and any other support required for data processing, management and analysis. This consultancy might involve multiple assignments across the duration of this framework agreement.

  1. Figure checking reports, press releases, blogs and other publications
  2. Provide ad-hoc analysis of the GCB data, both on the country level and respondent level to support the publication of regional GCB reports.
  3. Any other on-demand data analysis required to support the preparation and launch of TI’s global tools.


Selected external contributors will be offered to contribute on an occasional basis to the provision of ad-hoc data analysis support within an agreed upon timeframe.  TI-S will be responsible for the preparation of each specific assignment, including a detailed description of the assignment and its purpose, a description of the deliverable and a delivery date for each assignment. The TI Secretariat retains the sole rights with respect to all distribution, dissemination and publication of the deliverables.

All presentations and reports are to be submitted in English, in electronic form, in accordance with the deadlines stipulated above.
