International AS & A Level
Chemistry (2027)
Future 2027 revision: teaching from September 2027; IAS certification from August 2028; specification and codes pending publication
The current official subject page gives September 2027 first teaching and August 2028 IAS certification. Pearson's 5 October 2026 news says the specifications are due in the first half of 2027. The current catalogue says January 2028 first assessment, while the expressly provisional changeover table first shows new IAS in June 2028 and full IAL in June 2029; final dates remain unresolved.
StudyForA coverage: Planned
Original teaching and guided, independent and application practice have not yet been mapped for this entry. Official links below are resources, not completed StudyForA lessons.
Specialist review is pending. Self-check answers are learning support, not official exam marks or proof of mastery. Practical, oral, performance and coursework requirements, where applicable, need appropriate teacher or centre supervision and assessment.
Science changeover: provisional timetable
This timetable covers Biology, Chemistry and Physics. The 2026–2027 entry listings apply to the 2018 specification; they do not establish entries for the future 2027 route.
- 2018 IAS: the last regular series shown is October 2027; a resit series is shown for January 2028.
- 2018 IAL: the last regular series shown is January 2029; a resit series is shown for June 2029.
- 2027 IAS: the first series shown is June 2028.
- 2027 IAL: Unit 4 first appears in January 2029; the full route first appears in June 2029.
Pearson identifies the timetable as awaiting Qualifications approval. Confirm final assessment dates and entry eligibility with the centre.
Use one specification throughout; units from the 2018 and 2027 qualifications cannot be combined.
Publication dates for the new specification, scheme of work and sample assessments are still described as forthcoming. StudyForA has not verified the new award codes or mapped new teaching.

2027 specification publication and assessment status
Pearson’s 2026-10-05 update schedules the specifications for the first half of 2027. International AS and full International A Level are announced, but exact award titles, cash-in codes, unit combinations and final entry dates are not yet verified.
Pearson announces written assessment of practical skills and no additional live practical examination for the 2027 programme. The exact unit structure remains unverified until the specification is published.
Pearson strongly recommends students doing practical work themselves, rather than describing it as a formal requirement in this announcement. This is not evidence that StudyForA provides practical teaching or assessment.
Read Pearson’s dated science update ↗Entry checks still open
- The 2027 specification is not yet published in the reviewed official sources; Pearson schedules publication in the first half of 2027. Exact IAS and IAL cash-in codes, component/unit codes, unit titles, combinations and options remain unverified.
- The current Chemistry 2018 cash-ins XCH11/YCH11 and WCH11-WCH16 unit codes are legacy evidence only and must not be assigned to the 2027 revision.
- Pearson sources conflict on first assessment: catalogue January 2028 versus the provisional changeover table first showing IAS June 2028. The table awaits Qualifications approval; dates are not final entry availability.
- The provisional January 2029 IAL cell names Unit 4 only; it is not evidence of full IAL award/cash-in availability in that series.
- 2018 and 2027 specification units cannot be mixed. A calendar-2027 examination entry belongs to the current route rather than establishing a 2027-revision entry.
- Second-edition resources are announced for 2027, and their samples remain forthcoming. Listed product ISBNs do not establish final imprints, chapter maps, qualification coverage, teaching provision or formal assessment validation.
- Centre eligibility for the 2027 revision is not yet verified. Confirm Pearson’s final rules before selecting an examination route.
Confirm your specification and entry
Confirm the award, unit combination, examination year and centre eligibility. Listing in the catalogue alone does not establish that every unit is available in every examination series.

Announced resources for the 2027 revision
Pearson lists 7 resource products for Chemistry (2027). These announced second editions are separate from the resources for the current qualification. Confirm your specification and the product’s availability before ordering.

StudyForA teaching and guided, independent and application practice for this revision remain planned. These listings add no completed lessons or practice to the coverage totals.
