About this app

What is onetest? onetest is a rapid digital assessment that gives a snapshot of a child’s level in literacy and numeracy. It gives both an overall score and scores for individual subskills in literacy and numeracy. Who is it for? onetest is for use by Ministries of Education, teachers, researchers and implementation partners. Ultimately though, onetest is for the child. When key stakeholders can rapidly determine children’s literacy and numeracy levels, appropriate action can be taken to make a change that will improve children’s learning outcomes as soon as possible. The goal of onetest is to bring positive change for the child and their learning outcomes, by identifying which interventions are working, whether that’s on a national level or within a single classroom. Languages onetest is currently available in: Chichewa, Swahili, French for West and Central Africa, Portuguese for Mozambique, International English and American English. More languages will follow. How has onetest been developed and tested? onetest has been developed in-house at onebillion, with input from education experts and with our years of experience developing learning solutions that work for the child. Each localisation is created with input from local pedagogy experts to ensure quality is maintained in each new language. We are working with research partners to validate onetest against existing assessments to ensure accuracy.
