Education is one of the most important factors in determining future success. Everyone should have the same opportunity to receive an education and pursue their talents and interests!
On the whole, financially disadvantaged children have less access to education. 'Impact' describes what we want to improve for this target group and society as a whole. For example, we encourage interest in subjects like math which are crucual for many career paths, but cause issues for many students. The learning materials we provide allow for independent learning, thus helping students help themselves. Our target audience develops a positive attitude towards learning and cultivates own educational aspirations and goals. In the long term, we help ensure that all students finish school successfully and find personal and professional fulfillment.

Our impact chain

The following graphic summarizes what we want to achieve and what we need to do for it. Additionally we broke down in detail what problems we are addressing, what people we are reaching and what impact we want to have on our target group.

The Problem

The problem of education being only for the privileged is happening worldwide. Currently school systems force students to learn a certain amount of content in a set time period. Not all students study at the same pace which leads to more and more students needing tutors. In the UK every year parents invest £6 billion in private tuition. In Germany parents spend 879 Million Euros each year (Bertelsmann Stiftung 2016). Only the privileged can offered tutors, according to the PISA survey, education is very dependent on the parents’ income. The McKinsey Global Institute claims that in North America and Europe, companies will require 16 to 18 million more college-education workers than will be available in 2020.
