Analysis
Eleven chapters written to the revised National Curriculum 2023, structurally the broadest of the three boards' Biology 9 books: it adds Biomolecules, Reproduction in Plants and a full Biostatistics chapter ("biostatistic" occurs 28 times here against two in KP and one in Sindh). It also carries the corpus's cleanest edition-era tell - COVID-19 is defined substantively at p.36 and returns as the worked public-health example in the Biostatistics chapter at p.168, where no Sindh or KP science book mentions it at all. A1 is 3 for section 1.4, "Quranic Instructions to Reveal the Study of Life" (TOC PAGE 3), an assessed learning outcome - "State that the Holy Quran instructs to reveal the study of Life" (PAGE 5) - quoting Al-Anbiya 30 and Al-Nur 45 and glossing them as "the common origin and modification of animals". That gloss is the only place in the corpus where a board uses scripture to support an evolutionary framing. Equally notable is what Punjab dropped: it keeps the Quranic section but has no Muslim-scientist history-of-science section, which both Sindh and KP retain. A7 5 on absence - one female-marked token in 39,776 words.

Measured scores
Axes not listed were not scored for this book — coverage is uneven by design. All axes run 1–5, where 1 is the secular/pluralist/open pole. See the method.
Evidence recorded 1
Three kinds, deliberately styled apart. A quotation is verbatim wording and is only ever taken from English-medium text. An observation describes structure or theme — the only kind permitted for Urdu and Sindhi material, which this project never quotes. An absence is a negative result: a probe was run and returned nothing, which is the weakest claim made anywhere on this site.

The checksum is of the exact file these findings were computed from, so anyone can prove they hold the same bytes. The retrieval date is when this copy was fetched to the project's own disk, not a formal web-archive capture. Boards and mirrors reprint and reorganise continuously, so a source link may not resolve, and may not serve the same edition if it does. The bibliographic record above — board, class, subject, medium, curriculum, edition, approval reference and page count — is what identifies the book; the link is a convenience. This project does not republish the PDF itself, for the copyright reasons set out in about.
Identifiers and permanent link
| Record ID | pctb-biology-9-en |
|---|---|
| Permanent link | /books/pctb-biology-9-en/ |
| This record as data | /books/pctb-biology-9-en.json · whole dataset |
The record ID is an accession number that happens to be readable. It never changes, even if the metadata encoded in it turns out to be wrong — if this book's board, class, subject or medium is corrected, the correction appears in the fields above and the ID stays as it is. That is the only way a link made today still resolves in ten years. The full rule is in the standards.

If the edition is misidentified, a score does not survive its evidence, the source link is wrong, or a passage is unfairly characterised, that is worth reporting and will be acted on whether or not the correction suits the argument. Corrections are published in the corrections log, never quietly patched. This applies fully to the board that publishes this book: any reply will appear beside the finding it concerns, under the right of reply.
