INTRODUCTION
1.1. Research background
Since the first form of accreditation was introduced in 1989 in Western Europe
(Sursock, 2010), accreditation in higher education as a basic approach to quality
assurance has been greatly concerned by different stakeholders throughout the world. As
an inevitable trend, accreditation agencies have been established at both regional and
global scale (Nguyen & Nguyen, 2016).
With 295 higher education institutions (HEIs) and 1,823,991 students in the
academic year 2017-2018, Vietnam has focused on assuring the quality of education
(Nguyen, 2019). Its higher education (HE), therefore, is not an outsider in the global and
regional trends regarding quality assurance (Nguyen, 2019). Initially introduced into
Vietnam’s education and training in 1990s, accreditation was formalized in 2003 with
the establishment of the national organization in quality assurance and accreditation, the
General Department of Education Testing and Accreditation (GDETA) (Nguyen &
Nguyen, 2016). According to Education Law, it is compulsory for all higher education
institutions (HEIs) in Vietnam to be accredited since 2005 (Nguyen, 2014; Nguyen,
Oliver & Priddy, 2009). The accreditation model for HE system in Vietnam has been
adapted from those have been popularly utilized in regions, for example, ASEAN
University Network Quality Assurance (AUN-QA) and Bologna Process of Europe
(Nguyen & Nguyen, 2016). There are three components belonging to quality assurance
model in Vietnam including (i) internal quality assurance, (ii) external quality assurance
and (iii) accreditation agencies (Kristoffersen, 2010). With the aim to directing the
development of the quality assurance system, the Government of Vietnam has
promulgated legal frameworks as well as regulations for accreditation. Since 2007, the
Ministry of Education and Training (MOET) has issued the set of accreditation standards
for both program and institutional levels. Currently, the set of standards, adopted from
1
AUN-QA, included 11 standards, 50 criteria for programs by Circular 04/2016 and 25
criteria, 111 criteria for institutions by Circular 12/2017.
As a national leading HEI in Vietnam, VNU has great concern on accreditation
at both institutional and program levels. Six out of member universities have been
accredited by national standard of MOET with high results (MOET, 2019a). University
of Science (VNU-HUS) is the first university in ASEAN to be granted by AUN-QA
institutional standard (AUN factbook, 2018). Regarding the program accreditation, 29
programs have been awarded by international accrediting agencies, accounting for nearly
a quarter (23,02 percent) of total 126 programs that were internationally accredited
(MOET, 2019b). Thanks to the above-mentioned achievements, VNU possibly provides
invaluable experiences during the implementation of accreditation in terms of (i)
motivations and (ii) difficulties.
1.2. Problem statement
The accreditation of HE in Vietnam has achieved certain results (Nguyen, 2014;
Nguyen & Nguyen, 2016; Nguyen et al., 2017). MOET targets that all tertiary
institutions and at least 10 percent of programs will have been accredited by 2020
(MOET, 2014). 218 universities out of 295 higher education institutions (HEIs)
accounting for 73.9 percent conducted self-evaluation (MOET, 2019a). However, a
small ratio of HEIs and programs has been externally granted by accreditation agencies.
Until April 2019, regarding institutional level, 121 universities and 03 colleges out of
295, accounting for 42.03 percent, have been granted by domestic accreditation
certificates based on MOET standards (MOET, 2019a). 06 HEIs including VNU
University of Science out of 295, occupied 2.03 percent, have been recognized by
international accreditation organizations such as AUN-QA and High-level Council of
French higher education research and evaluation (HCERES) (MOET, 2019a). In terms
of program level, 142 out of 489 programs have been accredited, comprised of 29.04
2
percent (MOET, 2019b). There has been a mere proportion of 0.2 percent of programs
(16 programs) granted by national standards and a quarter (126 programs) granted by
regional and international standards (MOET, 2019b).
Additionally, arguments about the independence and effectiveness of
accreditation in Vietnam have been discussed in studies by Madde (2014) and Dao
(2015). The accreditation of Vietnam’s HE has faced with challenges including (i) low
quality awareness, (ii) limitation in human resources and (iii) unclear incentives for the
outcomes of accreditation (Thanh, 2013; Nguyen & Nguyen, 2016; Nguyen et al., 2017).
In order to meet target of all universities accredited by 2020, it is urgent to find
motivations to encourage HEIs to implement accreditation and the difficulties that hinder
the implementation of accreditation. As a leading comprehensive university that is
externally accredited by MOET and AUN-QA standards, VNU can be analyzed as a case
study.
1.3.Purpose of study
The thesis aims to identify the motivations to implement accreditation and
difficulties that hinder the implementation of accreditation at VNU. Based on the
analysis, the research then provides policy implications for public HEIs (institutional
level) and government/MOET (national level) to encourage public universities to
implement accreditation. To this end, VNU is taken as a case study.
1.4. Research questions
The research focuses on answering the following questions:
Question 1. What are motivations to implement accreditation at VNU?
Question 2. What are the difficulties that hinder the implementation of
accreditation at VNU?
3
Question 3. What are policy implications to encourage public universities to
implement accreditation?
1.5. Research method
With the aim to identify the motivations and difficulties to implement
accreditation, the thesis employs the qualitative method. Desk researches are expected
to be reviewed and secondary data are collected to introduce the current situation of
accreditation of Vietnam’s higher education as well as VNU. The policy documents of
accreditation at national level promulgated by the Government of Vietnam, MOET and
at institutional level by VNU and its members are analyzed.
In addition, in-depth interview is utilized. The author conducted the interviews
with 14 key informants that represent VNU level, its member level as well as ministerial
level of quality assurance and accreditation to deepen understandings of the research
issues. The interviews focused on (i) motivations and (ii) difficulties to implement
accreditation at VNU. Regarding VNU level, the thesis targets Director of Institute for
Education Quality Assurance (IFEQA) and Chief of Education Quality Assurance
Council to present the mindset of VNU leaders. As for VNU members, Directors/ViceDirectors and staff of Quality Assurance Centers (QAC) together with Vice Dean of
program have been interviewed to represent the perspectives of accreditation
implementers at VNU member universities/schools and faculties. In terms of ministerial
level, the author aimed to interview Vice-Director of Vietnam National University Center for Education Accreditation (VNU- CEA), which is first accreditation agencies
established in Vietnam by MOET and managed by VNU.
The findings of qualitative data in Chapter 5 including the motivations to
implement accreditation will be compared with theoretical framework mentioned in
Chapter 2 .

1.6. Significance of study
The thesis is expected to cover both social and academic significance.
Regarding academic significance, the thesis aims to provide a case study’s
analysis of accreditation based on the motivations and the difficulties that hinder the
implementation of accreditation at VNU. The findings of thesis might be the orientation
for the next research on the issues of accreditation in HE in Vietnam.
In terms of social significance, the motivations of VNU are expected to provides
policy implications at institutional and national levels to encourage public HEIs to
implement accreditation.
1.7. Limitations of study
An analysis of case study VNU - a leading university helps the research obtain
insightful understanding of accreditation within the institutional specific context.
However, the thesis merely focuses on the motivations and difficulties to implement the
accreditation at VNU – a case study example of a public HEI in Vietnam. Further studies
which identify the motivations of non-public HEIs are expected to be conducted. In
addition, the thesis aims to identify the institutional motivations of universities and
schools, therefore, motivations of lecturers and students that get directly benefits of
accreditation implementation are beyond the scope of this study. Moreover, the numbers
of interviewees are quite small (14 informants). However, thanks to their support, the
amount and quality of information is quite abundant and valuable.
1.8. Structure of the thesis
The thesis delivers six chapters including
Chapter 1. Introduction. This chapter will illustrate the research background
and state research problem. The research questions, research method, research
significance and limitations of study are also presented in this part.
5
Chapter 2. Literature review. Chapter 2 focuses on review the available
literature history of the research on accreditation in both international context and
Vietnam’s context.
Chapter 3. Research methodology. The objective of this chapter is to explain in
detail the research method of the thesis in detail.
Chapter 4. Accreditation of Vietnam’s higher education and Vietnam
National University, Hanoi. Chapter 4 aims to provide an overview of accreditation of
Vietnam’s HE. The policy documents at national level on HE accreditation,
characteristics as well as achievements and challenges of HE accreditation are
introduced. In addition, this chapter will focus on the overview and the achievements of
accreditation at VNU and its members. Policy documents on accreditation issued by
VNU and current situation on institutional and program accreditation will be also
provided in this chapter.
Chapter 5. Research findings. This chapter will present the finding results of
interview that identify the motivations and difficulties to implement accreditation. These
findings will then be analyzed and discussed in this part. In particular, the institutional
motivations at VNU are compared to the theoretical framework which has been
mentioned in chapter 2.
Chapter 6. Conclusion and policy implications. The final chapter will
summarize the main findings and discussions from above chapters and then provide
policy implications at institutional and national levels to encourage public HEIs in
Vietnam to implement accreditation.

LITERATURE REVIEW
2.1. Definition and concepts
There are a large number of definitions and concepts of HE accreditation. For
instance, Council for Higher Education (CHEA), the USA has defined accreditation as
“a process of external quality review created and used by higher education to scrutinize
colleges, universities and programs for quality assurance and quality improvement”
(CHEA, 2015). Accrediting Council on Education in Journalism and Mass
Communications (ACEJMC) regards accreditation as “a collegial process based on selfand peer assessment for public accountability and improvement of academic quality”. In
a broader context, UNESCO (2007) mentions that accreditation is “the process by which
a (non)-governmental or private body evaluates the quality of a HEI as a whole or a
specific educational program in order to formally recognize it as having met certain predetermined minimal criteria or standards” (cited in Nguyen & Nguyen, 2016). The result
of this process is usually the awarding of a status, of recognition, and sometimes of a
license to operate within a time-limited validity (UNESCO, 2007 cited in Nguyen &
Nguyen, 2016).
Some definitions related to school accreditation are introduced in both developed
countries and developing countries. In the U.S. setting, according to the Accrediting
Commission for Schools, Western Association of Schools and Colleges (ACS WASC),
accreditation is defined as “an ongoing cycle of quality and a process schools use to
monitor student learning and set school improvement goal”. The U.S. Department of
Education describes the practice of accreditation as “a means of conducting
nongovernmental, peer evaluation of educational institutions and programs” (Hegji,
2017). In the developing countries, for example, Nigeria defines school accreditation as
a type of school self-evaluation, a systematic and comprehensive evaluation to look out
for areas of strengths and weaknesses of the school (Afemikhe et al., 2015). In Vietnam’s
7
context, school accreditation is defined as the evaluation process including selfevaluation and external evaluation in order to determine the level the school satisfies the
educational quality evaluation standards, and recognize the school meeting educational
quality standards by government organizations (MOET, 2014).
There are some concepts including quality assurance, peer review, external
review and external evaluation and benchmarks related to accreditation. Quality
assurance as cited in IIEP-UNESCO (2011) is regarded as “a continuous process of
evaluating (assessing, monitoring, guaranteeing, maintaining, and improving) the quality
of a higher education system, institutions or programs.” According to MOET (2014),
quality assurance includes both internal and external review. It is confirmed that
accreditation is quality assurance through external review [12 V1]. External evaluation
is the third stage of accreditation process in Vietnam (MOET, 2014). Another concept is
peer review defined in Oxford dictionary as the evaluation of scientific, academic, or
professional work by others working in the same field. According to Massachusetts
Association of Planning Director, peer review is “the evaluation of creative work or
performance by other people in the same filed in order to maintain or enhance the quality
of the work or performance in that filed” (Hao, 2015). The differences between peer
review and accreditation is the objectives and scope of the concepts. Peer review aims
to support quality improvement or certify the level of achievement of the criteria while
the objectives of accreditation is to recognize the achievement of the standards.
Regarding scope, peer review is used for both individual and system levels while
institutional and program levels are granted by accreditation. For the benchmark, it is
“simply about making comparisons with other organizations and then learning the
lessons that those comparisons throw up” (European Benchmarking Code of Conduct,
cited in Focus, 2013). As can be seen in Figure 2.1, ANU-QA used benchmarking to
compare between the stakeholders’ need and the current accreditation implementation at
HEIs to identify the level of achievements that meet the ANU-QA criteria.

2.2. Theoretical framework
According Uno (2007), “motivation can be interpreted as an internal and external
impulse in a person indicated by the existence; desires and interests; encouragement and
need; hope and aspiration; appreciation and respect.” Machrony (2009) emphasized that
the objectives of motivation are to encourages activities, toward achieving needs that
satisfy or reduce imbalances. Dylan, 2018 introduced 6 types of motivations including
Intrinsic motivation, Extrinsic motivation, Incentive motivation, Fear-Based motivation,
Incentive motivation and Achievement-Based motivation. Intrinsic motivation is
stimulated by internal desires while extrinsic motivation is derived from external desires.
Fear-based motivation is generated by the accountability to public. Incentive motivation
9
focuses on the rewards that come after a goal is met while people utilize achievementbased motivation focus reaching a goal for the sake of achievement (Dylan, 2018)
Figure 2.2. Processes of motivational process
Source: Sung-il, 2013
Due to the limited researches on motivations of accreditation especially the
context of HE, the thesis only utilizes the theoretical framework of Neuroscientific
model and model to test accreditation stimulate change in Healthcare organization in
Canada Figure 2.2. explains the generation of motivation in terms of the reward-driven
approach process, regarded as an example of incentive motivation (Sung-il, 2013).
Figure 2.2 represents a complicated model but the thesis only focuses on the context of
accreditation applied to explore the impact of internal and external conditions. Later
findings of motivations generated from the implementation of accreditation at VNU in
chapter 5 will be compared to 6 types of motivations in theoretical framework in chapter
2.
