About NDDC Nigeria

The Niger Delta Development Commission is a federal government agency established by Nigerian president Olusegun Obasanjo in the year 2000 with the sole mandate of developing the oil-rich Niger Delta region of Nigeria.

• About The NDDC Scholarship 

• The Niger Delta Development Commission (NDDC) Scholarship is a program initiated by the Nigerian government to provide educational opportunities for students from the Niger Delta region. The Niger Delta region is known for its significant oil and gas reserves, but it has also faced numerous socio-economic challenges. One of the ways the government aims to address these challenges is by offering scholarships to qualified students from the region to pursue higher education overseas.
• The amount for the foreign scholarship shall be based on the prevailing exchange rate of the Naira.Current Application Closing Date is 3rd November, 2023.
  

  Application Procedure

• 1.The following documents must be attached to the application:
  2.Recent passport photograph
  3.Local Government Identification Letter
  4.Post Graduate admission letter from a recognized overseas university

About the NDDC Scholarship test format

NDDC overseas scholarship test was conducted by Cinfores-Ltd, between 2010 and 2015. Since 2016, the tests are now conducted by MEIL (MARG Educational International Limited).

The test usually comprises of 2 sections –

1. General questions which everyone will have to sit, and

2. Discipline-based questions.

For example, candidates in Engineering and Science related disciplines could take a mix of science-based questions like maths, English, physics and chemistry for part 1, then discipline-specific questions for part 2. The  test usually last between 30 to 60 minutes.
