National and International Education Indices and Surveys (ASER, UDISE+, PGI)
What to remember
- ASER is a citizen-led household survey by Pratham that checks whether rural children can really read and do simple arithmetic. UDISE+ is the official school-data system of the Ministry of Education. PGI is the official grading index that scores States and Union Territories on school education.
- Enrolment is not learning. UDISE+ counts schools, teachers and students; ASER and NAS/PARAKH check what children can actually do. A teacher must know which tool measures what.
- International studies (PISA, TIMSS, PIRLS) compare countries by age or grade; UNDP, UNESCO and the World Bank publish education indices and reports used in exams.
Why indices and surveys matter
Education planners need numbers to decide where to spend money. Teachers need numbers to know where children are weak. Three kinds of data are used.
- 1. Administrative data: counted from schools every year (UDISE+).
- 2. Learning surveys: test a sample of children (ASER, NAS, PARAKH Rashtriya Sarvekshan).
- 3. Performance indices: combine many indicators into one score or grade for a State (PGI).
A good teacher reads all three. Administrative data tells how many children are in school. Learning surveys tell how much they learn. An index tells how well the system is run.
ASER (Annual Status of Education Report)
- Run by the ASER Centre, the research wing of Pratham, a non-government organisation.
- It is a household survey, not a school survey. Trained volunteers visit homes in sample villages in rural districts. The idea is to reach children who are out of school or in any type of school.
- Children are tested one by one, orally, in their own home. The tasks are simple and are meant to be done by a child of Class 2 level.
- Reading tasks (in the child's language): recognise letters, read common words, read a short paragraph (Class 1 level), read a short story (Class 2 level).
- Arithmetic tasks: recognise numbers 1-9, recognise numbers 10-99, do a two-digit subtraction with borrowing, do a division of a three-digit number by a one-digit number.
- An English reading test (words and sentences) is also done in selected rounds.
- The key finding that made ASER famous: many children in upper primary classes cannot read a Class 2 text or do a simple subtraction. This is the idea of a learning crisis.
- ASER also reports on school facilities and children's access to digital devices in some rounds.
- ASER is not a government test. It does not rank schools. It gives a district-wise and State-wise picture of basic skills.
UDISE+ (Unified District Information System for Education Plus)
- It is the official database of the Ministry of Education (Department of School Education and Literacy).
- UDISE began as a merger of the earlier DISE (elementary schools) and the secondary-school data system. The "Plus" version is an online, real-time system introduced a few years later. Each school enters its own data through a web portal or app.
- It covers all recognised schools, from pre-primary and primary to Class 12, whether government, aided or private.
- Data collected: number of schools, school management type, enrolment by class, gender and social category, teachers and their qualifications, classrooms, toilets, drinking water, electricity, libraries, computers, and children with special needs.
- Each school and each child gets a unique code. The system now moves towards student-wise data (a child-level record that follows the student).
- Indicators computed from UDISE+ data:
| Indicator | Meaning | Remember |
|---|---|---|
| GER (Gross Enrolment Ratio) | All students in a level, whatever their age, as a share of the official age group | Can be above 100 |
| NER (Net Enrolment Ratio) | Only students of the official age in that level, as a share of that age group | Never above 100 |
| GPI (Gender Parity Index) | Girls' ratio divided by boys' ratio | 1 means equal |
| PTR (Pupil-Teacher Ratio) | Students divided by teachers | RTE norm is 30:1 (primary) and 35:1 (upper primary) |
| Dropout rate | Share of students who leave before finishing a level | Lower is better |
| Transition rate | Share moving from one level to the next | Higher is better |
| Retention rate | Share staying till the end of a level | Higher is better |
- For a Telugu-medium teacher, the practical point is simple: the head master or school nodal teacher fills UDISE+ data. Wrong data means wrong planning and wrong grants.
- UDISE+ is also used to calculate several PGI indicators.
PGI (Performance Grading Index)
- Developed by the Department of School Education and Literacy, Ministry of Education. It is meant to show where a State is strong and where it must improve.
- It was first released for a year in the late 2010s, and later rounds followed. The latest version is called PGI 2.0 and has a larger set of indicators.
- Structure of the original index: 70 indicators, 1000 points, grouped in two categories (Outcomes, and Governance and Management) and five domains.
- PGI 2.0: 73 indicators, 1000 points, with a new sixth domain on teacher education and training.
- Domains in PGI 2.0:
1. Learning outcomes and quality
2. Access
3. Infrastructure and facilities
4. Equity
5. Governance processes
6. Teacher education and training
- States and Union Territories are placed in ten grade bands. The top grade is Daksh and the lowest is Akanshi-3. Between them come Utkarsh, Ati-Uttam, Uttam, Prachesta-1, 2, 3 and Akanshi-1, 2. The names suggest effort and aspiration, so the lowest grade is a call to try harder.
- A district version, PGI-D, grades districts in the same spirit.
- The index tells States which domain pulls the total score down, so each State can plan its own improvement.
Other national tools a teacher should know
- NAS (National Achievement Survey): run by NCERT. It tests a sample of students in Classes 3, 5, 8 and 10 on language, mathematics, EVS or science and social science. It reports the percentage of children who reach the expected learning outcomes. The 2021 round was a large exercise covering districts across the country.
- PARAKH: a national assessment centre set up under NEP 2020, inside NCERT. The name stands for Performance Assessment, Review and Analysis of Knowledge for Holistic Development. It sets norms for assessment across all boards and runs the PARAKH Rashtriya Sarvekshan, which tests children at foundational (Class 3), preparatory (Class 6) and middle (Class 9) stages. The focus is on competencies, not on rote answers.
- NIPUN Bharat Mission: launched under Samagra Shiksha to make every child able to read with understanding and do basic numeracy by the end of Class 3. NIPUN stands for National Initiative for Proficiency in Reading with Understanding and Numeracy.
- Census literacy rate: a person aged 7 and above who can read and write with understanding in any language is literate. Kerala has long been the State with the highest literacy rate.
- NIRF (National Institutional Ranking Framework): a Ministry of Education ranking for higher-education institutions in categories such as overall, universities, colleges and engineering.
International education indices and studies
| Name | Run by | Who or what is measured | Frequency |
|---|---|---|---|
| PISA | OECD | 15-year-olds in reading, mathematics and science | Every 3 years |
| TIMSS | IEA | Mathematics and science, Grades 4 and 8 | Every 4 years |
| PIRLS | IEA | Reading comprehension, Grade 4 | Every 5 years |
| HDI (Human Development Index) | UNDP | Health, education and income; education uses mean and expected years of schooling | Yearly report |
| Global Education Monitoring (GEM) Report | UNESCO | Progress on SDG 4 | Periodic reports |
| Human Capital Index | World Bank | How much human capital a child born today will have | Periodic |
- PISA: India took part only once, in an early round, with two States. It has not taken part in later rounds. NEP 2020 aims to bring Indian assessment closer to such international standards.
- SDG 4 is the global goal on inclusive and equitable quality education and lifelong learning for all, to be reached by 2030.
- Learning poverty: a World Bank idea. It means the share of children at about age 10 who cannot read and understand a short simple text.
- Global university rankings such as QS and Times Higher Education are published by private organisations, not by the UN.
ASER, NAS and PGI compared
| Feature | ASER | NAS / PARAKH | UDISE+ | PGI |
|---|---|---|---|---|
| Run by | Pratham (NGO) | NCERT (government) | Ministry of Education | Ministry of Education |
| What it checks | Basic reading and arithmetic | Learning outcomes by class | School facts and enrolment | State-level performance grade |
| Where | Rural households | Schools (sample) | All recognised schools | States and UTs |
| Method | One-to-one oral test | Written test on sampled children | Online data entry by schools | Indicators from several sources |
Classroom angle
- Use ASER-style tasks in your own class: ask each child to read a short text and do a quick subtraction. This tells you who needs remedial help.
- Group children by actual level, not by class. This is the idea behind "teaching at the right level."
- Competency-based questions (NAS and PARAKH style) test understanding, not memory. Teachers should set such questions in unit tests.
- Keep school records accurate. UDISE+ numbers drive teacher posting, grants and school-mapping decisions.
Exam traps
- 1. ASER vs UDISE+: ASER tests learning, UDISE+ records facts about schools. Do not swap them.
- 2. ASER is a household survey in rural areas; NAS is a school-based sample test.
- 3. NAS is by NCERT; ASER is by Pratham; PGI and UDISE+ are by the Ministry of Education.
- 4. GER can exceed 100; NER cannot.
- 5. GPI of 1 means parity, not that all girls are enrolled.
- 6. PGI is a grading of States, not of individual schools.
- 7. PISA tests 15-year-olds; TIMSS tests Grades 4 and 8; PIRLS tests Grade 4 reading.
- 8. PISA is run by OECD; TIMSS and PIRLS by IEA.
One-liners
- 1. ASER stands for Annual Status of Education Report.
- 2. The ASER Centre is the research wing of Pratham.
- 3. ASER tests reading and arithmetic at about Class 2 level.
- 4. UDISE+ stands for Unified District Information System for Education Plus.
- 5. UDISE+ is an online system in which schools enter their own data.
- 6. PGI stands for Performance Grading Index.
- 7. PGI 2.0 has 73 indicators and 1000 points.
- 8. The top PGI grade is Daksh.
- 9. NAS is conducted by NCERT for Classes 3, 5, 8 and 10.
- 10. PARAKH is the national assessment centre under NEP 2020.
- 11. PISA is conducted by the OECD for 15-year-olds.
- 12. SDG 4 is the global goal for quality education.
