The handbook introduces visualization and measurement techniques related to impartiality and equality of condition, the requirements for the use of underlying data to measure both, and the advantages and disadvantages of each technique for generating insights into the magnitude and nature of any inequality. It provides solid examples of national efforts to track progress towards equity in both educational access and learning, highlighting positive country examples and stressing the need to include a wider range of dimensions of disadvantage in education plans. Finally, the handbook examines government spending on education to reveal who benefits, who misses out, and how resources could be redistributed to promote equity. It points out that in many countries, the children and young people who are the hardest to reach are often the last to benefit from government spending. It is simply more expensive to ensure their quality education, given the cost of measures to tackle the root causes of their disadvantage, from poverty to discrimination – and this should inform the distribution of resources.
