ABET—formerly known as the Accreditation Board for Engineering and Technology—is the globally recognized accreditor for engineering and technology programs at the post‑secondary level. Its criteria for Program Educational Objectives (PEOs) serve as the foundation of a systematic, outcomes‑based approach to engineering education. By establishing clear, measurable objectives that reflect both the institution’s mission and the needs of the profession, ABET ensures that graduates are prepared not only for immediate employment but also for long‑term professional growth and societal contribution. Understanding these criteria is essential for educators, administrators, students, and industry partners who are committed to maintaining excellence in engineering education.

What Are Program Educational Objectives?

Program Educational Objectives are broad, overarching statements that describe the professional and career accomplishments that graduates of an engineering program are expected to attain within a few years of graduation. Unlike student outcomes (which focus on what students know and can do at the time of graduation), PEOs look beyond the classroom into the real‑world trajectory of alumni. They answer the question: What kind of professionals do we intend our graduates to become?

Typical PEOs might include statements such as:

  • Graduates will be successfully employed in engineering positions or pursue advanced degrees.
  • Graduates will demonstrate leadership and ethical responsibility in their professional roles.
  • Graduates will engage in lifelong learning and adapt to evolving technological landscapes.
  • Graduates will contribute to society through engineering innovations or community service.

These objectives are deliberately broad because they capture the institution’s vision for its alumni over a longer time horizon—usually three to five years after graduation. They are informed by the mission of the institution, the expectations of employers, and the evolving needs of the engineering profession.

ABET’s Criteria for Program Educational Objectives

ABET’s accreditation criteria, found in the ABET General Criteria for Baccalaureate Programs, specify that each program must have published PEOs that are:

  • Consistent with the mission of the institution – The PEOs must align with the broader educational goals and values of the university or college.
  • Appropriate to the program’s discipline – They should reflect the specific competencies and professional expectations of the engineering field (e.g., civil, mechanical, electrical).
  • Measurable – While broad, the objectives must be structured so that the program can collect evidence of whether graduates are achieving them (e.g., via employer surveys, alumni questionnaires, or career tracking).
  • Based on the needs of the program’s constituencies – “Constituencies” include students, alumni, faculty, industry representatives, and other stakeholders whose input shapes the objectives.
  • Reviewed and revised periodically – ABET expects programs to have a formal process for reassessing and updating PEOs as circumstances change.

These criteria are not merely bureaucratic hurdles; they form the backbone of a continuous improvement cycle. Without well‑defined PEOs, it becomes impossible to measure the long‑term effectiveness of an engineering program or to identify opportunities for curricular enhancement.

Alignment with Institutional Mission

Every accredited engineering program operates within the context of a larger institution—a research university, a teaching‑focused college, or a polytechnic institute. The PEOs must naturally flow from the institution’s mission statement and strategic priorities. For example, a research‑intensive university might emphasize “graduates who lead interdisciplinary research teams,” while a teaching‑focused college might stress “graduates who excel in engineering practice and community engagement.” This alignment ensures that program‑level goals are coherent with the university’s identity and resource allocation.

Relevance to the Discipline

Engineering disciplines differ in their professional requirements, ethical codes, and technical standards. ABET expects that PEOs reflect the specific nature of the program. For instance, a civil engineering program might include an objective about “designing sustainable infrastructure that meets public health and safety standards,” whereas a computer engineering program might focus on “developing reliable, secure software systems.” Generic objectives that could apply to any major are discouraged; the PEOs should be tailored to the program’s field and the expectations of its professional societies, such as the American Society of Civil Engineers or the Institute of Electrical and Electronics Engineers.

Measurability and Evidence

Although PEOs are broader than student outcomes, they must still be measurable. Measurability does not mean a simple test score; rather, it means the program can gather data indicating progress toward the objective. Common measurement tools include:

  • Alumni surveys that track employment, graduate school enrollment, or professional certifications.
  • Employer satisfaction surveys that gauge graduates’ performance and leadership abilities.
  • Longitudinal studies of career progression, such as promotions or patents.
  • Feedback from industry advisory boards on the program’s overall direction.

A well‑designed assessment plan will define what constitutes satisfactory achievement for each PEO and specify how often the data will be collected and reviewed.

Time Frame: Three to Five Years After Graduation

ABET explicitly notes that PEOs are post‑graduation accomplishments. The typical evaluation window of three to five years allows alumni to establish themselves in their careers, complete graduate studies, or transition into leadership roles. This time lag distinguishes PEOs from student outcomes, which are assessed at or near commencement. Programs must design their assessment processes to capture data from graduates at the appropriate intervals, often through structured surveys emailed three to five years after graduation.

The Process of Developing Effective PEOs

Crafting meaningful PEOs is a collaborative endeavor that involves multiple stakeholders. ABET requires that programs demonstrate that their PEOs are developed and reviewed with input from constituencies. The typical process includes:

Identifying Key Constituencies

Constituencies are groups that have a vested interest in the program’s success. They typically include:

  • Students and graduates – Their firsthand experience provides realistic perspectives on what the program delivers.
  • Faculty – They understand the curriculum’s strengths and limitations.
  • Employers and industry advisory boards – They articulate current and future workforce needs.
  • Alumni – They can reflect on how the program prepared them for long‑term career success.
  • Professional societies and regulatory bodies – They set standards and ethical guidelines.

Programs often hold regular meetings with an advisory board comprising industry partners, alumni, and faculty. These meetings are a forum for discussing trends, challenges, and expectations that directly inform the PEOs.

Drafting and Revising Statements

Once stakeholder input is gathered, a drafting committee (often composed of faculty and key administrators) develops initial PEO statements. These drafts are circulated for feedback, refined, and finally approved by the program’s governing body. Best practices include:

  • Writing objectives that are specific enough to guide curriculum design, yet broad enough to remain relevant for several years.
  • Avoiding vague language like “becoming a successful engineer” without defining what success means in measurable terms.
  • Ensuring the set of PEOs collectively covers the range of professional aspirations (technical, ethical, social, and entrepreneurial).

After initial adoption, the PEOs should be reviewed every three to five years to ensure they remain aligned with changes in the profession, the institution, and societal needs.

Documentation and Communication

ABET expects that PEOs are published and readily accessible. Many programs display them on their website, include them in program handbooks, and discuss them during orientation. Transparency ensures that students, faculty, and employers all understand the program’s long‑term goals. The formal documentation should also outline the process used to develop and periodically review the PEOs, as ABET reviewers will examine this evidence during accreditation visits.

Assessing and Achieving Program Educational Objectives

Having well‑written PEOs is only half the battle. The real challenge lies in assessing whether graduates are actually meeting those objectives and using the results to improve the program. ABET’s criteria require a documented assessment plan that includes:

Data Collection Methods

Because PEOs are measured years after graduation, direct classroom assessment (e.g., exams, capstone projects) is insufficient. Instead, programs rely on indirect measures such as:

  • Alumni surveys – Asking alumni to self‑report their career outcomes, professional development activities, and satisfaction with their preparation.
  • Employer surveys – Soliciting feedback from supervisors on graduates’ performance, work ethic, and leadership.
  • Career tracking databases – Some universities maintain records of alumni employment, graduate school attendance, and awards.
  • Industry advisory board evaluations – Regular meetings where board members share anecdotal and quantitative insights.

Analyzing and Interpreting Results

Assessment data must be systematically analyzed to determine whether each PEO is being achieved. For example, if a PEO states that “graduates will be employed in engineering or related fields within three years,” the program would set a threshold (e.g., 90% employed) and then track actual employment rates. If the rate falls below that threshold, the program would investigate potential causes—perhaps a weak job‑placement office, outdated curriculum, or lack of soft‑skills training.

Closing the Loop: Continuous Improvement

The ultimate purpose of assessment is continuous improvement. ABET’s hallmark is the “plan‑do‑check‑act” cycle: after evaluating PEO achievement, programs must implement changes and then reassess. Examples of improvements driven by PEO assessment include:

  • Adding a professional ethics module after data showed that employers rated graduates low on ethical decision‑making.
  • Strengthening capstone design projects to better prepare graduates for the engineering design process.
  • Expanding career development services to improve job placement rates.
  • Revising PEOs themselves when they no longer reflect industry realities (e.g., shifting from “design” to “sustainable design” to meet environmental demands).

This feedback loop is what makes ABET accreditation a dynamic quality‑assurance system rather than a static checklist.

Importance of ABET’s Criteria for PEOs

Adhering to ABET’s criteria for Program Educational Objectives confers several interconnected benefits that extend far beyond the accreditation process.

Ensuring Graduate Readiness and Professional Success

When programs define and assess PEOs, they align their curricula with the competencies that industry and society value most. Graduates from ABET‑accredited programs are widely recognized as having a strong foundation in engineering science, design, ethics, and communication—exactly the skills that lead to long‑term career advancement. Employers often prefer to hire from accredited programs because the PEO framework gives them confidence that graduates are prepared for the challenges of professional practice.

Fostering a Culture of Continuous Improvement

ABET’s emphasis on assessment and revision prevents programs from becoming static. Faculty and administrators are encouraged to regularly ask: Are we meeting our objectives? How can we do better? This culture of self‑reflection leads to innovations in teaching, curriculum updates, and stronger partnerships with industry. It also helps institutions remain agile in response to rapid technological changes—for example, incorporating artificial intelligence or data science into traditional engineering disciplines.

Enhancing Institutional Reputation and Global Recognition

ABET accreditation is a globally recognized mark of quality. Engineering programs that meet ABET’s criteria—including robust PEOs—are often more attractive to prospective students, faculty, and funding agencies. Many countries, especially those that are signatories to the Washington Accord, recognize ABET‑accredited programs as substantially equivalent to their own national accreditation, facilitating international mobility for graduates. A clear, well‑implemented PEO framework demonstrates to peer institutions and employers that the program is rigorous and accountable.

Supporting Lifelong Learning and Societal Contribution

PEOs that include objectives related to lifelong learning, ethical responsibility, and societal impact encourage graduates to view their careers as more than just technical problem‑solving. By assessing whether alumni are engaging in continuing education, obtaining professional licenses, or volunteering in their communities, programs reinforce the idea that engineering is a profession with both technical and humanistic dimensions. This aligns with ABET’s broader goal of producing graduates who can address complex global challenges such as climate change, infrastructure renewal, and equitable access to technology.

Common Challenges and Best Practices

Despite the clarity of ABET’s criteria, many programs encounter difficulties when writing and implementing PEOs. Understanding these challenges can help institutions avoid common pitfalls.

Challenge 1: Objectives That Are Too Vague or Too Narrow

Some programs write PEOs that are so broad they become meaningless—e.g., “Graduates will be successful.” Success is subjective and nearly impossible to measure. Conversely, others make the objectives so specific that they become indistinguishable from student outcomes (e.g., “Graduates will be able to use finite element analysis”). The best practice is to strike a balance: objectives should describe accomplishments that are observable but not micromanaged. For example, “Graduates will advance into leadership roles within five years of graduation” is specific enough to track via surveys but broad enough to capture various career paths.

Challenge 2: Insufficient Stakeholder Input

If PEOs are drafted solely by faculty without input from industry or alumni, they may not reflect real‑world expectations. ABET reviewers carefully examine how constituencies are engaged. Best practice is to maintain a diverse advisory board that meets at least twice a year and to survey alumni and employers systematically. Documenting these interactions—through meeting minutes, survey instruments, and summary reports—is essential for accreditation evidence.

Challenge 3: Misalignment Between PEOs and Student Outcomes

Programs sometimes confuse the two. Remember: PEOs are post‑graduation achievements; student outcomes (now called “student performance indicators” under revised ABET criteria) are knowledge and skills obtained by the time of graduation. The curriculum and assessment plan must logically link the two—i.e., achieving the student outcomes should enable graduates to later achieve the PEOs. If there is a disconnect, the program should either adjust its student outcomes to better support the PEOs or revise the PEOs to be more realistic.

Challenge 4: Inadequate Assessment Planning

Even with well‑written PEOs, some programs fail to design a sustainable assessment cycle. They may collect data irregularly or rely entirely on alumni surveys with low response rates. Best practices include:

  • Using multiple sources of evidence to triangulate findings.
  • Setting target thresholds and monitoring trends over time.
  • Integrating assessment into existing processes (e.g., adding questions to course evaluations or advising surveys).
  • Assigning responsibility for assessment to a specific committee or coordinator.

Challenge 5: Resistance to Change

When assessment data suggests deficiencies, some programs are reluctant to implement changes, either due to resource constraints or faculty inertia. Overcoming this requires leadership commitment, transparent communication of assessment results, and a culture that values improvement over blame. Small, incremental changes are often more palatable than sweeping reforms.

Connection Between PEOs and Student Outcomes

To fully understand ABET’s criteria, it is helpful to clarify the relationship between Program Educational Objectives and Student Outcomes (often referred to as “program outcomes” or “graduate attributes”). ABET’s criteria for the 2024–2025 accreditation cycle (Criterion 3) lists seven student outcomes that every program must ensure its graduates possess, including the ability to apply engineering design, communicate effectively, and work in teams. These student outcomes are attained at graduation, while PEOs are attained after graduation.

The logical chain is as follows:

  1. The program develops a curriculum that enables students to achieve the student outcomes by the time they graduate.
  2. With those outcomes in hand, graduates enter the workforce or further education.
  3. Several years later, the program assesses whether those graduates have achieved the stated PEOs (e.g., are they working as engineers? Leading teams? Pursuing advanced degrees?).
  4. If PEO achievement is weak, the program examines whether the underlying student outcomes were adequate or whether the curriculum needs modification.

Thus, student outcomes serve as the building blocks for PEOs, and PEOs provide the long‑term validation that the program’s curriculum is effective. Both sets of criteria must be aligned for a coherent outcomes‑based education system.

Conclusion

ABET’s criteria for Program Educational Objectives are far more than an accreditation requirement; they are a strategic tool that helps engineering programs articulate their long‑term vision, engage with stakeholders, and commit to continuous improvement. By writing PEOs that are aligned with institutional mission, relevant to the discipline, measurable, and based on constituent needs, programs can ensure that their graduates are prepared to thrive in a rapidly changing world. The process of developing, assessing, and refining PEOs builds a culture of accountability and excellence that benefits students, employers, and society at large. For any institution serious about delivering a high‑quality engineering education, investing effort in understanding and implementing ABET’s PEO criteria is not just advisable—it is essential.
