The importance of girl child education is easiest to see if you follow one girl through her life. At each stage, school changes what is possible for her, and later for her own children.
This article takes that life-cycle view. It looks at what education gives a girl at 6, at 12, at 16, as a young woman and as a mother, using what research tells us at each step.
For a full overview of barriers and solutions, see our main guide on girl child education.
Age 6: Starting Primary School
At six, school gives a girl the basics: reading, writing and numbers. It also gives her friends, routine and a safe place to spend the day.
- Literacy: the skill that unlocks all other learning.
- Confidence: answering in class and being praised for effort.
- Health: many schools offer health checks, deworming or meals.
What families can do: enrol daughters on time, buy the same supplies for girls and boys, and read with them at home.
Age 12: Moving to Secondary School
This is where many girls are lost. The move to secondary school often means longer journeys, higher costs and more household duties.
Yet secondary education is where the biggest gains come. According to World Bank research reported by Theirworld, each extra year of secondary school raises a girl’s future earning power by about 18%.
What families can do: plan for secondary school costs early, look for girls’ stipends, and arrange safe travel with friends or relatives.
Age 16: The Danger Years
In the mid-teens, two big risks can end a girl’s education: child marriage and early pregnancy.
In Bangladesh, UNICEF reported in October 2026 that nearly one in two girls is married before age 18, based on the Multiple Indicator Cluster Survey 2025. UNICEF says child marriage pushes girls out of school and raises the risk of early pregnancy. It calls for every girl to complete secondary school.
School also protects. The United Nations has stressed that education is critical in preventing adolescent pregnancy. Read more in our article on parental education and teen pregnancy.
What families can do: keep daughters in school through SSC and HSC, refuse early marriage proposals, and talk openly with daughters about their plans.
Age 20: A Young Woman With Choices
A girl who finishes secondary school has many more options:
- university or college
- technical and vocational training
- a paid job with better pay and conditions
- starting a small business
She is more likely to choose when and whom to marry, and when to have children.
Age 30: An Educated Mother
Here the benefits spread to the next generation. Educated mothers are more likely to:
- vaccinate their children and seek health care early
- feed their children a healthy, varied diet
- help with homework and talk with teachers
- keep both daughters and sons in school
That is why people often say: educate a girl, and you educate a family.
The Importance for Society
- Economy: more women in skilled work raises national income.
- Health: fewer child deaths and better nutrition.
- Equality: more women in leadership and decision-making.
- Peace and stability: educated communities are better able to solve problems together.
Common Myths About Girls’ Education
