Separate structural-engineer license: Illinois regulates Professional Engineers and structural engineers under different licensing acts and rules. This page addresses the Illinois Professional Engineer license only.
Qualifying Education
Activities must advance professional engineering knowledge or skills
Programs must enhance professional skills or scientific knowledge, foster general or specialized engineering practice and values, be developed and presented by qualified persons, and identify course objectives and content.
Common qualifying activities
College or university engineering courses
Professional engineering courses and programs
Seminars, tutorials, workshops, and short courses
Online and in-house courses
Technical or professional meeting presentations
First-time teaching or instructing
Qualifying papers, articles, patents, and society service
Selected limits and conversions
1 PDH = at least 50 minutes
1 CEU = 10 PDH
1 semester hour = 15 PDH
1 quarter hour = 10 PDH
First-time teaching = 3 PDH per presentation hour
Paper, presentation, or patent = 10 PDH under applicable conditions
Board, committee, or society-office service = maximum 8 PDH per cycle
Providers: Acceptable structured-education providers include NCEES, NSPE, ISPE, ACEC-Illinois, ASCE, colleges and universities, and technical or professional organizations—including manufacturers—whose programs relate to professional engineering. IDFPR does not preapprove individual courses.
Online and Self-Study Education
Online courses can satisfy the PE requirement
Illinois expressly recognizes successful completion of online courses and does not state a separate numerical cap for online PDH earned by Professional Engineers. The course must meet the same relevance, instructor, objective, content, and documentation standards as other qualifying education.
A self-study course receives credit only when the licensee completes an examination that is graded by the sponsor. This makes a documented online course with a graded assessment different from unverified personal reading or viewing.
Carryover and Waivers
Carryover is limited by both date and subject
Conditional carryover
Up to 15 qualifying PDH earned from June 1 through November 30 of the renewal year and not used for that renewal may be carried into the next cycle. The hours must be recorded on the Department-issued carryover form.
Core hours cannot carry
Illinois statutes and rules, professional conduct or ethics, and sexual-harassment-prevention training must each be completed during every prerenewal period and cannot be satisfied with carryover.
First renewal
A PE is exempt from reporting PDH during the first biennial renewal period in which initial Illinois licensure was obtained. All later renewal periods are subject to the requirement.
Military or hardship
Qualifying active military duty may support a waiver. Disability, illness, or another clearly mitigating circumstance may support a documented request for waiver, additional time, or a modified education schedule.
Nonresident PEs: Illinois-licensed engineers residing and practicing elsewhere must still meet Illinois requirements. Substantially equivalent hours used for another jurisdiction may also be applied toward Illinois.
Documentation and Audit
Retain complete supporting records for six years
Renewing PEs certify that they have complied with the PDH requirement. IDFPR may select licensees for random audit and require additional evidence. The licensee must retain records or otherwise be able to produce them.
A log by itself is insufficient. Supporting documentation should identify the provider, hours, date, location or delivery method, subject matter, and proof of attendance or completion.
