FOREWORD
The review of the field of science and technology (FOS) classification was 
discussed several times in
the framework of the last revision of the Frascati Manual (FM). In 
particular, it was felt at the time that the
FOS classification, the most appropriate classification for R&D in the 
public sector, needed to be reexamined
in order to reflect the latest changes in the science and technology area, 
especially with regard to
emerging technology fields such as ICT, biotechnology and nanotechnology.
Following these discussions, in 2002, the Working Party of National Experts 
on Science and
Technology Indicators (NESTI) decided to set up a Task Force to work on the 
revision of the FOS
classification. The OECD Task Force was led by Jan C. G. van Steen (the 
Netherlands) and included
Australia, Norway, Portugal, as well as EUROSTAT and UNESCO.
During the process, several drafts were discussed by NESTI. The Ad Hoc 
Meeting on Biotechnology
Statistics was also consulted. However, owing to the different perspectives 
of the scientific community,
administrative systems, and users of the classification, and to the dynamics 
of science itself (such as the
emergence of interdisciplinary sciences), it was not possible to develop a 
FOS classification that satisfied
the needs of all actors involved. As a result, the final classification 
represents a compromise between
different viewpoints and user needs.
The Committee for Scientific and Technological Policy (CSTP) was invited to 
declassify the
document under the written procedure. This was completed in June 2006.
This document is published under the responsibility of the Secretary-General 
of the OECD.

REVISED FIELD OF SCIENCE AND TECHNOLOGY (FOS) CLASSIFICATION IN THE
FRASCATI MANUAL
Background
The Frascati Manual (FM) 2002 deals with the FOS classification in Chapter 
4.4, par. 273-276.
Table 3.2 contains the FOS classification itself. The FM recommends that the 
major fields of science and
technology should be adopted as the functional fields of a science 
classification system. This classification
should be used for the R&D expenditure of the government, higher education 
and PNP (Private NonProfit)
sectors - and if possible of the BE (Business enterprise) sector - and for 
personnel data in all
sectors. However, the current implementation can be characterised as quite 
diverse across countries.
The existing FOS classification does not fully reflect changes in the 
science and technology area,
especially with regard to emerging technology fields such as ICT, 
biotechnology and nanotechnology.
This, as well as the need to obtain better coverage of the data based on the 
FOS, the most appropriate
classification for R&D in the public sector, motivated the NESTI Group to 
review the classification.
However, it is not realistic to think that it is possible to develop a FOS 
classification that satisfies the needs
of all actors involved. This is due to different perspectives of the 
scientific community, administrative
systems, and users of the classification and to the dynamics of science 
itself (such as the emergence of
interdisciplinary sciences). Therefore, the final classification represents 
a compromise between different
viewpoints and user needs represented by NESTI.
The review of the field of science and technology (FOS) classification was 
discussed several times in
the framework of the last revision of the Frascati Manual. In its 2000 
meeting NESTI concluded that the
FOS classification ought to be reviewed, but it was not until 2002 that 
NESTI decided to set up a Task
Force to work on this specific issue. The Task Force was composed of 
Australia, the Netherlands (lead
country), Norway, Portugal, as well as EUROSTAT and UNESCO. The OECD 
Secretariat took a
co-ordinating role.
At the 2004 NESTI meeting, a first draft of the revised FOS classification, 
prepared by a consultant
and reviewed by the Task Force, was discussed [Secretariat working document
DSTI/EAS/STP/NESTI(2004)26]. Although the proposal was appreciated to some 
extent, a number of
critical comments were made. It was concluded that the Task Force would take 
into account those and
additional written comments in order to ensure a well described 2-digit 
classification rolling up to the
present 1-digit reporting categories.
A second draft of the FOS classification was tabled at the NESTI meeting in 
2005 [Secretariat
working document DSTI/EAS/STP/NESTI(2005)15]. After a lengthy discussion, 
the group approved the
revised FOS classification pending some changes discussed at the meeting and 
to be submitted in written
form. NESTI also decided to seek the advice of the OECD Ad Hoc Meeting on 
Biotechnology statistics on
the best way of classifying biotechnology within the FOS and to take into 
account a recommendation in
this respect.
A number of written comments were received after the NESTI meeting, some of 
which were taken on
board, some not. The Ad Hoc Meeting on Biotechnology statistics was also 
consulted, which led to the
recommendation to split up biotechnology into four components to be assigned 
to three different 1-digit
DSTI/EAS/STP/NESTI(2006)19/FINAL

FOS fields (two were classified under Engineering and Technology, one under 
Medical Sciences and one
under Agricultural Sciences). The persons who commented were given feedback 
on the way their proposed
changes were incorporated. The final version was sent to the Task Force for 
a last round of checks and
endorsement of the changes made. The revised classification is presented in 
Annex 1. A comparison of this
version with the one included in the Frascati Manual 2002 is presented in 
Annex 2.
The remainder of this document illustrates the principles guiding the 
revised FOS classification,
presents its content and identifies the implications of its implementation 
in the FM (2002). The
classification has not been changed at the first digit level (six major 
fields), which is the level at which
variables are collected in the MSTI questionnaire at the moment, in order to 
ensure the continuity of time
series for the purpose of international comparisons. The novelty consists of 
a breakdown at the 2-digit level
that takes into account emerging and interdisciplinary fields, and for which 
internationally comparable data
are sought. Each 2-digit category is accompanied by a description of its 
content to aid bridging the 2-digit
international classification with the more detailed national 
classifications.
Principles for a revised classification
A number of guidelines for the revised classification were outlined by NESTI 
in 2004 and further
discussed by the Task Force. The following principles for the revised FOS 
classification were outlined:
. The major 6 fields were sub-categorised into the 2-digit level (see Annex 
2).
. "Other" categories were attached to every major field in order to keep the 
classification flexible
and allow for the appearance of new areas of studies.
. The "other" categories of engineering and technology, social sciences and 
humanities in the FM
2002 were split into several sub-categories.
. In particular, "bio-technology" and "nano-technology" were newly 
introduced in the
"Engineering and technology" field.
. Data collection and reporting of the major six fields guarantee 
international comparability of the
R&D data over time.
Implementation of the revised classification in the Frascati Manual
The revised international classification will have implications for many 
different areas of interest
(R&D surveys, R&D projects, policy issues). The implementation of the FOS 
classification will depend on
a number of factors:
. The purpose for which the classification is used (monitoring, evaluation, 
allocation of funds).
. The different possible actors using the classification (government, 
research councils, universities,
international organisations, others).
. The specific relationship between the government and the institutions in 
the higher education and
government sectors).
. The extent to which institutions are able and willing or can even be 
induced to deliver the data.
. The administrative burden on the institutions concerned.

As a first step, the implementation of the classification will require 
changes to the OECD R&D
questionnaire and subsequently it will influence data collection in OECD 
countries. It is envisaged that
countries supply data for the different sectors at the 2-digit level of the 
classification. This implies that the
R&D questionnaire will need to be changed to incorporate the 2-digit 
reporting categories. However, some
member countries will find it difficult, at this stage, to report R&D data 
at the more detailed 2-digit level
of the FOS. Hence, the 1-digit will still appear in the experimental table 
for those countries that will not,
initially, be able to deliver such data, and in order to preserve continuity 
of time series at the 1-digit level.
Conclusions and next steps
A distinction should be made between national and international purposes in 
using classifications. The
classification contained in Annex 1 does not aim at harmonising data 
classified by field of science and
technology for national purposes, rather it aims at achieving a minimum 
level of comparability of R&D
data at the international level. Moreover, there is a balance to be achieved 
between the - often detailed -
needs of the users on the one hand, and the need to minimise the 
administrative burden on statistical offices
on the other hand. Furthermore, R&D surveys are not the best suited to 
collect very detailed data
(alternative sources can be used such as databases at project level in 
countries and databases with
publication and citation data).
For these reasons a pragmatic approach in drafting the classification was 
taken and an effort was
made to keep the number of 2-digit categories low rather than high. Avoiding 
trend breaks was also an
important consideration and the final version tries to stay as close as 
possible to the existing FOS
classification.
Furthermore, progress of science and technology on the leading edge is very 
fast, so that new and
emerging multi- or inter-disciplinary areas will need to be classified in 
the future in order to measure R&D
inputs and performances. The current FOS classification is not necessarily a 
final one but will need to be
revised regularly, as in the case of the Frascati Manual that was revised 
after ten years of implementation.
Empirical studies can aid in improving the basis of the FOS classification.
The NESTI group will be expected to follow closely the developments in 
science and technology and
the evolving user needs at the national and international level in order to 
review the FOS classification
when needed.
