Overview
ISO/IEC TS 20748-4:2019 - "Information technology for learning, education and training - Learning analytics interoperability - Part 4: Privacy and data protection policies" specifies privacy and data protection requirements and attributes to inform the design and operation of learning analytics (LA) systems and practices. It is part of the ISO/IEC 20748 series and targets schools, universities, workplace learning and blended learning settings. The Technical Specification frames privacy as a combined social and technical concern (privacy and data protection) and provides attribute-level guidance to support interoperable, privacy-aware LA solutions.
Key topics and technical requirements
- Scope and purpose: Defines privacy and data protection principles tailored to the learning, education and training (LET) context.
- Privacy concepts and definitions: Clear definitions for terms such as PII (personally identifiable information), PII controller/processor, anonymization, pseudonymization, consent, sensitive PII, and accountability - drawn from ISO vocabularies and related frameworks (e.g., ISO/IEC 29100, ISO/IEC 20889).
- Requirements structure: Organized into:
- Clause 5 - privacy and data protection requirements (general and LET-specific issues)
- Clause 6 - LA privacy and data protection attributes
- Clause 7 - detailed attribute specifications (core characteristics, information collection/processing/dissemination principles, consent, governance and accountability)
- Consent and documentation: Principles for consent as an ongoing process, timing of consent, consent frameworks and minimum data requirements to document consent for LA data sharing.
- Data handling techniques: Guidance on anonymization, pseudonymization and limited use of sensitive data to reduce privacy risk.
- Accountability and governance: Requirements for institutional codes of practice, roles of data controllers/processors, and governance models that support transparency and explainability.
Practical applications and users
This specification is practical for:
- System developers building learning analytics platforms who need to embed privacy-by-design attributes and interoperable metadata about privacy characteristics.
- Educational institutions (schools, universities, corporate training) drafting LA privacy policies, consent workflows, and institutional codes of practice.
- Third-party providers and vendors delivering analytics services who must document processing roles, guarantees (anonymization/pseudonymization), and consent handling.
- Compliance and governance teams aligning LA operations with legal and ethical frameworks (e.g., GDPR, FERPA, OECD/APEC principles).
Practical uses include producing privacy attribute specifications, designing consent UIs and audit trails, defining minimal PII collection, and formalizing accountability arrangements.

Introduction
The ISO/IEC 20748 series clarifies and regularizes the behaviour of components related to learning
analytics interoperability. Privacy and data protection are identified as important cross-cutting
requirements impacting all sub-processes of learning analytics (LA). Even if privacy and data protection
are regulated by law in some jurisdictions, there is a need to specify privacy requirements as part of
this series to establish principles that can influence design and operation of learning analytics systems.
The concepts of privacy and data protection are used differently around the world. In this document,
which is designed to be used in an educational setting, ‘privacy and data protection’ are used as
one concept to capture both the social and contextual aspects of privacy and the more technical
and managerial aspects of data protection for learning, education and teaching (LET). Privacy and
data protection requirements for learning analytics can be derived from multiple sources, both
written and non-written, including educational policy frameworks, ICT infrastructure principles,
international privacy frameworks (e.g., OECD, APEC, European Union), trade agreements, national
legal frameworks, ethical principles observed in LET, etc. These requirements are often expressed as
high level principles that different constituencies could agree upon. This document develops detailed
privacy and data protection attributes pertaining to the learning analytics process cycle (described
in ISO/IEC TR 20748-1). This document enables the development of LA privacy and data protection
attribute specifications, which detail how information exchange should be performed to fulfil the aims
of LA operations without compromising privacy and data protection of the individual.
This document is intended to inform system developers in designing LA systems and processes
supporting inclusive privacy and data protection policies. The primary beneficiaries of privacy and
data protection policies are the individuals who share their PII, in this case the students (and their
parents or guardians), teachers and other actors who take part in learning, education and training.
Educational organizations and third party providers are also target user groups.

5 Privacy and data protection requirements
5.1 General
As the field of privacy and data protection for learning analytics is new and evolving, the specifications
in this document will only address a subset of all issues an organization needs to handle in setting
up a learning analytics service. This document comprises discussion of requirements (Clause 5), a set
of privacy and data protection attributes (Clause 6) and a number of attributes selected for further
specification (Clause 7).
5.2 The concept of privacy and data protection in LET
What privacy entails is difficult to define restrictively as privacy means different things in different
countries around the world. What is seen as an intrusion into the private life or affairs of an individual,
and whether gathering of data about the individual is seen as undue or illegal, varies with cultural
context.
The approach taken in this document is, therefore, to look at privacy problems in a LET context to
be able to specify privacy and data protection principles for LET that address specific problems and
support a good learning environment for the individuals involved.
Privacy is the right of an individual to keep oneself and one’s information concealed or hidden from
unauthorized access and view of others. The composite concept of privacy and data protection used
in this document refers to the capacity to control when, how and to what degree information about a
person is communicated to others in a particular context or setting. The capacity to control can lie with
the individual, with the context, or both.
Some information is, however, of a more sensitive nature and is, in many jurisdictions, subject to
special protections. Such sensitive data may include racial or ethnic origin, political opinion, religious
or philosophical beliefs, trade union membership, genetic or biometric data, health data, or data
concerning sex life or sexual orientation.
NOTE ISO/IEC 29100:2011, Table 2 gives a list of examples of attributes that can be used to identify natural
persons, some of them being sensitive personally identifiable information.
Use of sensitive data in LET implies a greater risk against privacy and data protection; therefore, in
LA, sensitive data should play a limited role and be used only after explicit consent is given by the
individual.
Often in learning, education and training, long-term, deep relationships are built between the student
and teachers, fellow students, etc. where PII is exchanged. These relationships are potentially of
great benefit for the individual; however, in some cases, the release of PII could also be of great harm.
Therefore, handling of PII by the educational institution must be justified by clearly stated principles.
In LET, we find a variety of justifications for processing data about a person (e.g., consent, contract,
legal obligations, vital interests, public interests, and legitimate interests of the organization). Lack of
clarity of justification for collection of data about a person can threaten privacy and data protection; as
can other issues that are typical for LET:
Justification of collecting data: The data processor or data controller (e.g., institution, teacher, researcher)
could have a legitimate interest (and their own justification) to process data about a person; however,
the limits to the resulting permission to process data (by enrolment to school, a course, etc.) might not
be clear.
Purpose of processing data: If collection of student data is limited to support for learning, using the data
to sell things to students is excluded. However, the scope of learning is unlimited, which makes further
purpose limitation difficult.
When to ask for consent: Learning consists of an infinite number of small steps, often interacting with
others over time. Some of these steps involve acting on the analysis of data that the individual should
4 © ISO/IEC 2019 – All rights reserved
have consented to being collected and processed. However, sometimes data processing is the right of
the organization as part of a contract. To offer consent to an individual when the institution already has
the right to process such data is wrong. To act on processed data when the individual should have the
opportunity to consent to be involved is also wrong. In long-term and close relationships, as in LET, it is
not always easy to draw the line between these two scenarios.
Notification: Age of the students, the educational setting, matters of authority, and other reasons could
influence how notification of data collection and processing will be conceived. The educational context
is, however, an opportunity to clarify privacy and data protection issues related to use of LA.
In LET, privacy and data protection is accomplished by the application of a set of fair information
principles which seek to ensure that:
— only accurate, relevant and timely information (personal and otherwise) is collected and/or
exchanged among the actors involved in LET;
— all uses of information are known and appropriate;
— personally identifiable information (PII) is protected.
There are some aspects of LET that will impact on how privacy and data protection will be dealt with
in this setting:
— Attending school might be mandatory. In that case, the school is authorized by law or by the context
to collect and process data about the student.
— In many cases, education is based on a long-term relationship, to institutions, teachers, fellow
students, and others. This might impact on how long data can be kept.
— In most LET settings we find persons with the role to protect students and to know more about
potential threats to the individual.
— For underage students, parents have the right to be involved in many questions that concern privacy
and data protection for students.
— Learning and knowledge-seeking are without boundaries, the unplanned and unexpected will
impact the student journey. Therefore, it is difficult to limit in advance the purpose of collecting
data from learning activities.
— Experimentation, play and identity testing is part of education. Therefore, PII is more likely to be
shared in educational settings than in settings with a more defined set of roles, e.g., the workplace.
— Openness and trust play an important role in LET. Therefore, in a good learning environment one
finds more information about persons than in settings where there is less openness and trust.
These requirements should be further developed, keeping sound pedagogical principles in mind, based
on the emergence and evolution of proper practice in the field of learning analytics. It should also
be noted that even if students are the primary stakeholders of LET, data will also be collected about
teachers and others supporting learning. The privacy and data protection interests of all parties should
also be appropriately addressed.
In general, these challenges to privacy and data protection in LET settings present the following high
level requirements to ICT systems:
— Support for transparency giving the actors in LET insights into how PII is handled in different
systems.
— A processing regimen that allows the individual, where appropriate, to actively manage PII
considering age, educational context and legal requirements.
— Data protection policies and systems ensuring privacy, confidentiality and security.

5.3 Privacy and data protection issues related to learning analytics
In developing ISO/IEC TR 20748-1 and ISO/IEC TR 20748-2, a use case-led design process identified the
following general requirements for learning analytics applications.
For the student:
— tracking learning activities and progression;
— tracking emotion, motivation and learning-readiness;
— early detection of student's personal preferences;
— improved feedback from analysing activities and assessments;
— early detection of student non-performance (mobilizing remediation);
— personalized learning path and/or resources (recommendation).
For the teacher:
— tracking students/group activities and progression;
— adaptive teacher response to observed student's needs and behaviour;
— early detection of student disengagement (mobilizing relevant support actions);
— increasing the range of activities that can be used for assessing performance;
— visualization of learning outcomes and activities for individuals and groups;
— providing evidence to help teachers improve the design of the learning experience and resources.
For the institution:
— tracking class/group activities and results;
— quality assurance monitoring;
— providing evidence to support the design of the learning environment;
— providing evidence to support improved retention strategies;
— support for course planning.
These educational requirements from ISO/IEC TR 20748-1 and ISO/IEC TR 20748-2 show that the value
of privacy and data protection of the individual is ensured in serving the student first, as well as the
systems that support the student.
ISO/IEC TR 20748-1 defines privacy and data protection requirements as impacting on all processes
in a LA cycle. In Figure 1 the process model from ISO/IEC TR 20748-1 is used as a scaffold to develop
privacy and data protection attributes (Clause 6).

added preparation and management processes related to privacy requirements
5.4 Privacy framework requirements
Privacy and data protection requirements are found in national or state legislation, which vary in
different jurisdictional domains. Privacy legislation is often based on, or aligned with, international
guidelines, of which OECD, in 1980, provided the first internationally agreed collection of privacy
principles. This document derives requirements for privacy and data protection from three
international privacy frameworks, recognized in many countries:
— the privacy principles of the 35 countries of the Organization for Economic Co-operation and
Development (OECD),
— the privacy framework of the 21 countries of the Asia-Pacific Economic Cooperation (APEC), and
— the General Data Protection Regulation (GDPR) of the 31 countries of the European Union/European
Economic Area.
In Table 1 the privacy principles defined in the OECD, APEC and GDPR frameworks are compared.

Table 1 shows that the three frameworks are heavily influenced by each other and share many of the
same concepts. All frameworks try to strike a balance between the protection of the individual and the
free flow of trade. Processing data for LA must be guided by the overall aims of supporting learning
and the contexts in which learning occurs. Processing has the potential also to create harm; therefore,
LA implementers should have measures in place to ensure a positive balance to benefit the individual
and minimize potential harm. In addition, the data collection, processing and dissemination processes
should be adjusted accordingly to benefit, reduce risks, and cause no harm to individuals.
6 Learning analytics privacy and data protection attributes
A privacy and data protection attribute is a specification of a privacy and data protection requirement
related to a learning analytics process. In this document, privacy and data protection attributes are
developed by matching user requirements to LA processes described in ISO/IEC TR 20748-1. For this
purpose, the requirements from the most recent international privacy framework (EU GDPR), are
