Indicator 1: Adult Literacy Rate: 15+ Population Definition
Adult literacy rate is defined as the percentage of the population aged 15 years and over who can both read and write with understanding a short simple statement on his/her everyday life. Generally, the term ‘literacy’ embraces also ‘numeracy’, the ability to make simple arithmetic calculations. The adult literacy rate reflects the accumulated achievement of primary education and adult literacy programmes in imparting basic literacy skills to the population, thereby enabling people to apply such skills in daily life and to continue learning and communicating using the written word. Literacy represents a potential for the individual’s further intellectual growth and enhanced contribution to socio-economic and cultural development of society. Unit of Measurement
Percentage of the
population aged 15+ that is literate Discussion
A high adult literacy rate suggests the
existence of an effective primary education system and/or adult literacy
programmes that have enabled a large proportion of the population to acquire
the ability of using the written word (and making simple arithmetic
calculations) in daily life. It is common practice to present and analyse
literacy rates together with the absolute numbers of adult illiterates, because
improvements in literacy rates may sometimes be accompanied nevertheless by
increases in the illiterate population, due to the changing demographic
structure. See Also

Methodology
Yes Method of Collection
Collected as a part of Census of India operations once in ten year. The information is collected from the head of the household who is the main respondent. The collection is based on complete enumeration, as all the households of the country are included in the census operations. The Office of the Registrar General of India conducts census. A few estimates on literacy rates are also available on housed hold sample basis. These surveys are conducted by the National Sample Survey Organisation. Known Indicator Limitations
Since the census is conducted once in ten
year, the literacy figures in intermediary years based on complete enumeration
is not available. The information is
based upon the responses of the head of the household. Generally, tests are not conducted to know
abilities of the literate population. Indicator 2: Literacy Rate: 15-24 Years Old Population Definition
The number of persons aged 15-24 who can both read and write with understanding a short simple statement on their everyday life, divided by the population in that age-group. The literacy rate of the 15 to 24 year-olds has a special significance in reflecting the recent outcomes of the basic education process. It is a summary measure of the effectiveness of the education system. Unit
of Measurement Percentage of the
population aged 15-24 years that is literate Discussion
A high literacy rate among the 15-24 year olds suggests a high level of participation and retention in primary education, and its effectiveness in imparting the basic skills of reading and writing. Because persons belonging to this age group are entering adult life, monitoring their literacy levels is important in respect to national human resources policies, as well as for tracking and forecasting progress in adult literacy.

Indicator 3: Literacy Gender Parity Index Definition
The ratio of the female to male adult literacy rates measures progress towards gender equity in literacy and the level of learning opportunities available for women in relation to those available to men. It serves also as a significant indicator of the empowerment of women in society. Unit of Measurement
Ratio of female to male literacy rate
Discussion
When the literacy gender parity index shows a value equal to one, female literacy and male literacy rates are equal. A value less than one indicates that proportionately fewer women than men have basic literacy skills, and conversely, a value exceeding one indicates that proportionately fewer men have basic literacy skills. Note that the value of the gender parity index may be affected by differences in the life expectancy between men and women, especially for the older age groups where women on average live longer than men. In such cases, one should derive literacy gender parity indices by age groups. See Also

4: Expenditure on Adult and Continuing Education to Total Expenditure on
Education
Definition
Government expenditure for adult and continuing education expressed as a percentage of total government expenditure on education. This indicator shows the relative share of expenditure on adult and continuing education within overall government expenditure on education. This indicator should be based on consistent data on government expenditure for each level of education that cover public funding for both government and private educational institutions Unit of Measurement
Percentage to total
public expenditure on education Discussion
A relatively high percentage of government expenditure devoted to adult and continuing education denotes the priority given to this sector in national educational policies and resource allocation. When interpreting this indicator, one should take into account the corresponding literacy rates for population aged 15+ and 15-24 years See Also

Methodology
Yes Method of Collection
Collected by the Department of Education, Ministry of Human Resource Development, Government of India as a part of regular collection of annual statistics. Within the Department, the Division of Planning, Monitoring and Statistics is entrusted this task which disseminates data through their annual publications that contain state-specific information. The structured Data Capture Formats are used to collect information. Information is collected on school basis and all the recognised institutions are included in the collection. At present, the publication containing financial statistics is latest available for the years 1994-95 to 1996-97. This contains actual statistics for 1994-95, revised estimates for 1995-96 and budget estimates for 1996-97. Known Indicator Limitations Time lag is the main limitation. Other major limitation is that the
private expenditure on education is not covered. However, all the private
institutions recognised by the Government are covered in the annual collection
of statistics. Indicator 5: Villages without Pre Primary Education Facility Definition

Percentage to total
number of villages Discussion
The percentage of villages without pre primary education facility indicates a state’s capacity to prepare young children for primary education and should be viewed in relation to gross enrolment in early childhood care education programmes (age 3-5 years). A high enrolment ratio indicates adequate capacity for this type of programme See Also

The indicator is not readily available but can be developed from the information generated by the NCERT as a part of its All-India Educational Survey, Sixth survey being the latest one with September 30, 1993 as its date of reference. The information is collected on habitation basis and all the habitations of the country are included. Information on this indicator is inclusive of the private unrecognised institutions, which are otherwise, do not form part of the regular collection of statistics Known Indicator Limitations
Since the NCERT survey is conducted once in 5-7 years, the indicator is not available on regular basis. There is no other source of this indicator. Indicator 5a: Enrolment in Pre Primary Education Institutions (ECCE) Definition
Enrolment in pre primary education institutions including government, private, and community programmes. Unit of Measurement
Absolute Number Discussion
The enrolment in ECCE programmes should be viewed over time so that growth in enrolment be measured. The indicator should also be viewed in relation to gross enrolment ratio in early childhood care and education programmes (age 3-5 years). A high enrolment ratio indicates adequate capacity for this type of programme. A gross enrolment ratio approaching or surpassing 100 per cent also indicates that a state is, in principle, able to accommodate all children in the official age group concerned by ECCE. See Also

institutions.
Indicator 6: Gross Enrolment Ratio for Age-group 3-5 Years Definition
Total number of children enrolled in early childhood care and education programmes, regardless of age, expressed as a percentage of the population in the relevant official age group i.e. 3-5 years. This indicator measures the general level of participation of young children in early childhood care and education programmes. It also indicates a state’s capacity to prepare young children for primary education. Unit of Measurement
Enrolment (Gross) in ECCE centres expressed as a percentage to the population in the age-group 3-5 years Discussion
A high gross enrolment ratio in early childhood care and education programmes indicates adequate capacity for this type of programme within the country. A gross enrolment ratio approaching or surpassing 100 percent indicates that a state is, in principle, able to accommodate all children in the official age group concerned by ECCE. See Also

Within the Department, the Division of Planning, Monitoring and Statistics is entrusted this task which disseminates data through their annual publications that contain state-specific information. The structured Data Capture Formats are used to collect information. The official statistics includes only the pre primary recognised institutions and hence the information is not complete. The other governmental departments (women and child development ) also run a variety of early childhood centres (balwadi, anganwadi etc.) apart the private unrecognised schools/centres which may also be large in number. Known Indicator Limitations
The indicator is not readily available. In order to develop it, complete information on enrolment in ECCE centres is required which is not available on regular basis. Apart from the enrolment, the indicator also needs projected population of age group 3-5 years, which is generally not available. Population is available for the census year only, hence, the same needs to be projected in a year for which the enrolment is available. A slight over/under estimation of population may change the GER dramatically. Indicator 7:
Primary Grade I Pupils having attended some form of organized Early Childhood
Care Education Programmes Definition Number of new entrants to primary grade I who have attended some form of organised early childhood development programme equivalent to at least 200 hours, expressed as a percentage of total number of new entrants to primary grade I. This indicator helps to assess the proportion of new entrants to grade I who presumably have received some preparation for primary schooling through ECCE programmes. The percentage of new entrants to primary grade I who have attended some form of organised early childhood development programme cannot exceed 100 per cent. Unit of Measurement
Percentage of new entrants to primary grade I who have attended some form of organised ECCE programmes Discussion
A high percentage of new entrants to grade I of primary education who have attended some form of organised ECCE programme indicates that a large proportion of these children have participated in organised learning activities prior to entering primary school. Progress in schooling is often associated with cognitive abilities acquired at young ages. It is commonly recognised that prior participation in ECCE programmes can play an important role in a child's future education, because they shape attitudes toward learning and develop basic social skills, but the effect of ECCE activities on children’s cognitive development may vary according to the programme attended. However, this indicator may give an exaggerated picture of access to ECCE, since those children who have access to ECCE programmes are also more likely to have access to primary schools See Also

Percentage of
habitations having population 300 and more and served by primary schooling
facilities within a distance of 1 km. Unit of Measurement
Percentage to total
number of habitations having population 300 and more Discussion
To know whether the existing schooling
facilities are equally available or not, indicators of access are used. While
analysing accessibility, a number of factors, such as, distance from the house,
mode of travel and time need to reach school are considered. Generally, a
primary school is supposed to be available within one kilometre from the
habitation. Habitation is treated as the lowest unit of planning where
schooling facilities are likely to be available. In addition, percentage of rural population served by schooling
facilities within 1 km. may also be considered as an indicator of access. See Also

Primary schools are the institutions, which impart education up to grade IV/V and are normally accredited to or sanctioned by some public authority and is known as recognised schools. A recognised school is one in which the course(s) of study followed is prescribed by the government. It runs regular classes. The official entry age for primary education usually varies between five and six years. In principle, this level covers about four/five years of full-time schooling. Primary education constitutes the first cycle of compulsory education. Unit of Measurement
Absolute Number Discussion
Number of primary schools over time may be useful to know the growth that is being taking place. This serves only limited purpose unless it is linked to number of habitations and rural population having access to primary schooling facilities. The growth in primary schools should be linked to growth in upper primary schools. The policy directives in this regard are one upper primary school for every three primary schools, which should be examined over time to have real pattern of opening of schools. Since, education of girls is one of the major concerns in most of the states, the number of schools opened separately for girls may also be useful to analyse so as its rural and urban distribution.

reveal that infrastructural facilities in school help to attract children and
also to retain them in the system. Along with the building, its type should
also be analysed. Schools buildings are classified under `pucca’, `partilay pucca’, `kachcha’, `thatched huts’, `tents’
and `open space’. Other facilities, in school, such as, drinking water,
toilet facilities, electricity, separate toilet for girls, playground, number
of instructional rooms and school boundary should also be analysed. See Also
