How to Apply to Chemistry at Lehigh University: The College of Arts and Sciences Offers a Chemistry BS (ACS-Certified per the Website), BA, Biochemistry and Pharmaceutical Chemistry, with Early Decision on 1 November, No Early Action and Optional Testing, for Domestic, International (Including Chinese) and Transfer Applicants

Lehigh University is in Bethlehem, Pennsylvania. Undergraduate chemistry is offered by the Department of Chemistry in the College of Arts & Sciences, and chemistry degrees are also offered in the P.C. Rossin College of Engineering and Applied Science (see below). Here is what you need to know for fall 2027 entry, based on the University’s admissions site, the College of Arts and Sciences and the chemistry department’s websites, organised for US domestic applicants, international applicants and applicants from China, followed by transfer students. Biology, chemical engineering, medicine and pharmacy are not covered in this article.

1. Degrees and how to apply

• Degrees (chemistry department “Majors and Minors” page): B.S. in Chemistry, B.A. in Chemistry, B.S. in Biochemistry, B.S. in Pharmaceutical Chemistry, and a minor in chemistry (16 course credits). The department’s undergraduate page lists an “ACS certified BS Chemistry major”, and says students take courses in the five sub-disciplines: analytical, biochemistry, inorganic, organic and physical chemistry.
• The chemistry B.S.: it begins with the first-year course Chemistry 40 & 41, with an integrated advanced laboratory (workstation-based molecular modeling and computer-interfaced experiments), averaging about 30 students and designed for those considering chemistry-oriented degrees; the first three years introduce the breadth of the classical areas, and the fourth year is largely open for specialisation, which may be combined with graduate-level courses or courses outside chemistry such as business. The page says the department has defined “an essential core of ten chemistry courses that every chemistry major should take”, with additional courses for specialisation in areas such as analytical/physical, materials, health professions, pharmaceutical, polymers and business.
• The chemistry B.A.: the College of Arts and Sciences B.A. is not a pre-professional program; it suits students who do not plan graduate work in chemistry or allied sciences but want a stronger chemistry background than the minor, and can be tied to health-related, environmental or geochemistry or chemistry-management options. Its basic requirements are the same as the B.S., and students may switch between the B.S. and B.A. as late as the junior year; B.A. students who decide on graduate school should talk to an adviser about extra coursework.
• The B.S. in Biochemistry: an interdepartmental degree in the College of Arts and Sciences overseen by a committee of faculty from the Departments of Chemistry and Biological Sciences; students may register through either department (the biochemistry program page says “Biochemistry majors should be declared in Biological Sciences”); Lehigh currently has no biochemistry minor. It is covered in the biology article and not repeated here.
• The B.S. in Pharmaceutical Chemistry: described as a chemistry degree option focused on core chemistry, biochemistry and molecular biology for careers in the pharmaceutical field.
• Which college: the department page says chemistry degrees are offered in both the College of Arts and Sciences and the College of Engineering and Applied Science, while biochemistry degrees are offered in Arts and Sciences only; the engineering-side requirements and admission details are not covered here.
• How courses are taught: the department page says several courses use interactive group study, such as a studio in introductory chemistry, workshops in organic chemistry and project groups in the analytical and physical laboratories; the department takes part in the University’s Co-op Program, and overseas study is best done in the junior year; some students with significant advanced placement have completed B.S./M.S. programs in four years, including two summers.
• How to apply: through the Common Application or Coalition Application with Scoir. The admissions FAQ refers to “the four undergraduate colleges”, and the requirements page mentions an “Intended College or Program” drop-down in the application (in the note on the seven-year dental program). Whether to choose Arts and Sciences or Engineering when applying for chemistry, whether admission is by major and whether there is a major-specific cut-off are not stated in the pages read; ask Admissions.
• When and how to declare the major: the department page links a “Declare a Major in Chemistry and Biochemistry” form but does not state the timing, any grade requirement or any cap on places; the University’s course catalog is hosted on a third-party (CourseLeaf) platform and is not covered here, so check the catalog or contact the department (inchm@lehigh.edu). The sample academic plans for each degree are Google spreadsheets, which are not covered here. The advising page says each major has an assigned adviser and students should keep an academic plan and share it with the adviser.

2. Prerequisites and course planning

• Minimum high school courses for all applicants (admissions FAQ): English 4; foreign language 2 (waived only in exceptional cases for otherwise well-qualified candidates, for any of the four undergraduate colleges); social science 2; laboratory science 2; college-preparatory mathematics 3; elective subjects 3; 16 credits in total. The office says most admitted students exceed these minimums.
• High school chemistry, physics and calculus: neither the admissions pages nor the chemistry department pages state how many years of high school chemistry or physics, or whether calculus, the major needs; this is not published there, so ask Admissions or the department. Only the University-wide minimum of 2 years of lab science and 3 years of college-preparatory mathematics is given.
• The chemistry sequence: see above; the list of the ten core chemistry courses and the mathematics and physics requirements are in the University’s course catalog, which is not covered here.
• AP/IB and credit: the admissions FAQ says the Registrar reviews college-level credits earned in high school after admission; the international page says students with IB higher-level scores of 5 or better, or A or B at A Level, may be granted credit, with credentials evaluated individually for course equivalency. Which Lehigh courses AP Chemistry, IB chemistry or AP Calculus correspond to is not published. The transfer page tells admitted transfer students that AP Chemistry needs a 5 and IB higher-level scores of 6 and 7 (section 8), which differs from the international page’s IB 5; rely on the credit evaluation after admission.
• Laboratories: the department page describes an advanced laboratory in introductory chemistry, workshops in organic chemistry and project groups in the analytical and physical laboratories; a separate page on chemistry laboratory safety is not covered here.
• Undergraduate research: the department page says 70% of chemistry and biochemistry majors choose research; students may start as early as the first year, but many are advised to wait until the second semester of the first year or the fall of the sophomore year, after foundational coursework; it advises reading faculty research descriptions and emailing faculty before preregistration, and says each registered research credit typically corresponds to about three hours of work per week. Forms of involvement (volunteer, independent study, honors, summer research) vary by research group.
• Departmental honors in chemistry: six credit hours of 300-level research, a written report and a presentation to a three-person committee; students form the committee about a year before graduating, submit an intent-to-participate form at least two semesters before graduating, and must complete the defence by the Thursday of week 14 of the last semester; honors students are recognised at the department’s awards ceremony in spring. The detailed requirements are in a PDF that is not covered here.
• Student groups: the department page mentions social events with professional groups such as ACS and AXE.
• Chemistry competitions: the admissions pages read do not say how chemistry olympiads or similar competitions are viewed.

3. Application rounds, deadlines and materials (fall 2027 entry)

• Rounds (admissions “How to Apply” and “Admissions Requirements” pages): Early Decision I is due 1 November with a decision in mid-December; Early Decision II is due 1 January with a decision in mid-February; Regular Decision is due 1 January with a decision in late March. Both Early Decision rounds are binding. Lehigh has no Early Action. The pages show no year, so check that the dates apply to fall 2027 entry.
• How to apply and the fee: the Common Application or the Coalition Application with Scoir, with Lehigh’s questions and writing supplement; the application fee is $75. An interview is not required; the office says interviews are for students with specific questions or who want to add context, and that every interview is evaluative and goes into the file.
• Materials: a School Report (including the counselor recommendation) and official high school transcript, one teacher recommendation, a mid-year report and transcript, and a final transcript after graduation (from a high school with a CEEB code). The website does not say the teacher must teach a science subject; this is not published.
• Testing: SAT/ACT submission is optional indefinitely; scores from several dates are superscored; an ACT taken with the science section must be reported in full. Applicants who report scores must have official scores sent by the College Board or ACT before classes start, and any discrepancy can lead to admission being reversed.
• How applications are read: the office says every application is reviewed holistically and lists factors including class rank, grades in the context of the school, grade trends (especially senior-year courses), performance in courses related to the intended area of study, course difficulty, recommendations, extracurricular or work experience (with emphasis on leadership) and demonstrated interest in Lehigh.

4. US domestic applicants

• Costs (2026-27, admissions “Tuition, Aid & Affording College” page): tuition $69,420; typical first-year housing $11,470; full meal plan $7,760; technology fee $630, activity fee $290, wellness fee $250; the page lists a total of $89,820. Students in certain programs and majors pay an additional $910 (the page names an Engineering and Science fee, an Arts and Sciences fee or a Health fee). Lehigh is a private university and the page does not distinguish in-state from out-of-state tuition.
• Aid and scholarships: the page says undergraduates from families with total income below $75,000 are eligible for a full tuition grant through the Lehigh Commitment; 26% of students admitted for 2025-26 received a merit scholarship of $15,000 or more a year; and $175 million is available in grants and scholarships. Aid application deadlines (financial aid table): ED I 1 November, ED II 1 January, Regular Decision 15 January. The admissions office’s Early Decision note says ED I applicants send the CSS Profile and tax documents by 1 November and ED II applicants by 15 January, and all aid applicants must submit the FAFSA and CSS Profile by 1 February; the two pages give different ED II aid dates (1 January and 15 January), so check them.
• Priority or guaranteed admission for Pennsylvania residents: not stated in the pages read.
• Testing policy: see section 3.

5. International applicants

• Who counts as international: anyone who is not a US citizen, wherever they attend high school; “eligible non-citizens” for federal aid (such as permanent residents and refugees) are treated as domestic, and US citizens living abroad apply as domestic students. Applicants must be completing or have completed the equivalent of 12 years of primary and secondary education, or the programme that leaves them eligible for university study in their own system; students who have only completed O level or GCSE/IGCSE study are not eligible and should apply in the final year of A level study or the equivalent.
• English proficiency: required unless English is your first language or your last two full years of formal instruction (not counting the current year) were in English. TOEFL and IELTS are preferred; the TOEFL iBT Home Edition and the Duolingo English Test are considered if those exams are not available; scores must come directly from the testing agency; the most competitive candidates score above 90 on the TOEFL, 7.0 on the IELTS or 120 on Duolingo. The international page also gives guidance bands: scores that generally indicate strong readiness are TOEFL iBT 95+ (tests before 21 January 2026) or 5.5+ (new format from 21 January 2026), IELTS 7.5+ and Duolingo 120+; scores that may suggest a need for additional support are TOEFL iBT 86–94 (new format 4.0–5.0), IELTS 6.5–7.0 and Duolingo 110–119; scores below those ranges raise considerable concern. The first-year section of the requirements page mentions only the TOEFL 90 and Duolingo 120 lines, not an IELTS line. SAT and ACT scores cannot meet the English requirement.
• Proof of funds: the international page says no bank statement or certificate is needed at the time of application; it is requested if you are admitted and decide to enrol.
• Financial aid: admission of non-US citizens is need-aware. Non-citizens who need aid must submit the CSS Profile ($25 fee); if that fee is a significant hardship, the ISAFA may be submitted instead, but places are limited and the CSS Profile is strongly preferred. The CSS Profile or ISAFA is due by the application deadline: ED I 1 November, ED II and Regular Decision 15 January. The first aid offer is final apart from adjustments for increases in the cost of attendance, and aid is not adjusted for changes in your home currency. The international page says tuition, room and board can exceed $98,900 a year; its FAQ and the requirements page say $93,400; both figures are on the website. The page says merit scholarships range from $5,000 to full tuition with no separate application.
• Application fee waiver: a non-US citizen whose family can contribute no more than $10,000 a year and for whom the fee is a hardship can request a waiver in the Common Application or Coalition Application using the code printed on the international page.
• International students on campus: the international page says that in 2024–2025 Lehigh hosted 967 international students from 87 countries, 352 of them undergraduates; the Office of International Students and Scholars (OISS) provides visa documents.

6. Applicants from China

• Gaokao: neither the international page nor the requirements page mentions whether the gaokao is considered or how it is used, and there is no China-specific page; this is not published there. You can ask the international admissions office (luinternational@lehigh.edu).
• Transcripts and school documents: the website gives only the general international requirements (section 5) and the 12-years-of-education requirement; whether there is a specific format for Chinese high school transcripts or school-leaving examinations is not stated.
• English and funds: follow the English bands and aid rules in section 5.

7. Outcomes and contact

• Careers (chemistry department “Undergraduate” page): the page lists jobs a chemistry bachelor’s degree can lead to, including analytical chemist, medical doctor, chemical instrumentation developer, patent law, dentist, petroleum research, drug development and manufacturing, pharmaceutical chemist, chemical engineering, pharmacist, environmental protection, physician’s assistant, food researcher, quality control and assurance, forensic chemistry, research and development, formulation chemist, industrial chemist, synthetic chemist, materials scientist and teaching. The pages print no employment numbers or salary data specific to chemistry. At University level the cost page prints “$77K average starting salary of 2025 graduates”, which is University-wide, not chemistry data.
• Contact: the chemistry academic coordinator, inchm@lehigh.edu, Seeley G. Mudd, Room 697.
• Chemistry-specific undergraduate scholarships: not stated in the department pages read.

8. Transfer students

• Deadlines: fall entry 1 April (decision in mid-May); spring entry 1 November (decision in late December). The pages show no year, so check that they apply to fall 2027 entry. Apply through the Common Application or Coalition Application with Scoir; the fee is $75; there are no transfer interviews; the SAT and ACT are not required.
• GPA: there is no minimum GPA, but competitive applicants typically have 3.25 or above. Applicants must be in good academic standing at their current institution.
• Materials: the final high school transcript, transcripts from every college attended, a Conduct Report Form (sent directly by the previous institution) and the fee. The website says Lehigh does not require course descriptions, but the Registrar will ask if more information is needed, and the transfer page advises supplying course descriptions and syllabi where possible.
• Credit transfer: credit is evaluated by Registration & Academic Services after admission, in consultation with departments on specific equivalencies; only grades of C or better transfer (C- never does); pass/fail courses do not transfer; no more credit than shown on the original transcript is awarded; transfer grades are not counted in the Lehigh GPA. For admitted transfer students, most AP scores of 4 and 5 and most IB higher-level scores of 6 and 7 can count for placement and credit (Calculus AB, Chemistry and both English exams require a 5).
• Chemistry: the pages read do not state requirements for entering the chemistry major, whether earlier coursework can replace required chemistry courses, or the prerequisite chemistry sequence; the transfer page says AP Chemistry needs a score of 5 to earn credit (see below). Transfer students should contact the Department of Chemistry (inchm@lehigh.edu).
• International transfer students: applicants from institutions where English is not the main language of instruction must submit a WES evaluation; the English bands are TOEFL 90, IELTS 7.0 and Duolingo 120.
• Scholarships: academic or talent-based scholarships for transfer students are described as limited; admitted transfer students who are Phi Theta Kappa members receive $10,000 a year.
