Framed as a binary choice, this question tends to produce analysis paralysis — schools spend weeks weighing classroom-ready content against homegrown material as if picking one meant permanently ruling out the other. In practice, the schools that get the most value out of a reading program rarely make an exclusive choice at all. They treat the question as a resourcing decision made unit by unit, not a single strategic commitment made once at the start of the year and never revisited.
The case for Classroom-Ready Packs
Speed, consistency, and access to a cross-school daily competition your own content can't join. No writing, editing, or levelling workload on your staff.
The speed advantage of Classroom-Ready Packs isn't just about the first week — it compounds every time a school wants to add a new theme, level, or story count without pulling a teacher away from actual teaching to source and level new content. A department that relies entirely on homegrown material effectively re-runs that sourcing cost every single term, whereas a pack-based approach only asks for that effort once, when a school decides to add its own material for something genuinely specific to its community.
The case for your own stories
Local relevance, your school's values and language, and material tied directly to what you're already teaching in class.
The case for original material isn't just about local color for its own sake — it's that certain content can't come from anywhere else. A story built around a specific local festival, a historical event significant to the school's country, or a values conversation tied to the school's own mission statement has no equivalent in a general-purpose global library, no matter how large that library grows.
Aligning school packs with your teaching calendar
The strongest reason to write original content isn't local flavor for its own sake — it's timing. A school pack can be built to follow the same sequence as the year's actual curriculum: a story about ecosystems timed to the science unit that covers them, a story about a historical period running alongside the history unit studying it, a values-themed pack matched to the school's own character-education calendar for that term. Reading stops being a subject that happens in parallel to everything else a student is learning, and starts reinforcing it directly.
This kind of alignment is difficult to get from a general-purpose global library, since a pack built for broad use across many schools can't be timed to any single school's specific calendar. It's realistic, though, for a school's own authored content, precisely because the school controls both the curriculum and the pack — the two can be planned together from the start rather than matched up after the fact.
Why most schools do both
Global packs cover breadth and the competitive element quickly; school-authored packs cover what's specific to your community — run side by side, not as a replacement for each other.
The reason most schools land on a mixed approach rather than picking one path exclusively is that the two options solve different problems well. Global packs solve breadth, consistency, and access to a cross-school competitive element efficiently. School-authored packs solve something global content structurally can't: alignment with a specific school's own annual or termly curriculum, so the reading journey runs alongside the student's actual learning journey rather than as a disconnected parallel activity.
A practical split that tends to work
A common and workable pattern is to run global packs for the bulk of weekly reading — covering breadth of level and theme, and giving students access to the daily inter-school competition — while reserving school-authored content for a smaller number of flagship units tied to specific local events, values, or curriculum moments the school wants to own directly. This keeps the sourcing workload manageable while still giving the program a distinct local identity where it matters most.
Who should actually write school-authored content
The most sustainable school-authored content usually comes from teachers who are already planning a themed unit for other reasons — a national holiday, an assembly topic, a values-week focus — rather than from a dedicated curriculum-writing exercise done separately from regular teaching. Piggybacking story creation onto planning that's happening anyway keeps the additional workload closer to zero than trying to schedule separate writing time.
How to think about the long-term balance
Over several years, most schools find the ratio between global and school-authored content shifts gradually toward more original material, not because global packs become less useful, but because a school's own library of authored stories grows naturally as teachers create new units term by term. Planning for that gradual shift from the outset, rather than expecting either extreme to remain fixed, tends to produce a more sustainable long-term program.
How to budget staff time for the mixed approach
A useful planning rule is to treat school-authored content as a fixed, small time allocation per term rather than an open-ended commitment — for instance, one flagship unit per term, written by whichever teacher already has a relevant theme in their existing lesson plans, with the story, discussion questions, and any local vocabulary drafted in a single planning session rather than spread across several weeks. Treating original content creation as a bounded, predictable task rather than an ongoing open commitment is what keeps the mixed approach sustainable term after term, as opposed to becoming one more unbounded item on an already full teaching workload. Schools that skip this step and simply ask teachers to "add some of our own stories when they have time" tend to see original content creation stall after the first term, precisely because there's no fixed scope or deadline attached to it.
Where iRead differs: Both pack types share the same games, quizzes, and CEFR-level tagging, so mixing global and school-authored packs adds no separate administrative system to maintain — it's a content decision, not a technical one.

Compare pack typesKey takeaway
Treat this as an ongoing resourcing decision made per unit, not a single upfront commitment — the schools getting the most value tend to lean on Classroom-Ready Packs for breadth and consistency, while reserving original writing for the handful of units where local relevance matters more than convenience.
Frequently asked questions
Who writes school-authored stories?
Usually English teachers or a curriculum coordinator, using iRead's story editor — games and quizzes attach automatically.
Can school packs also be CEFR-levelled?
Yes — schools tag their own stories by level the same way global packs are levelled.
How much original content does a school typically need to feel distinct?
There's no fixed ratio, but many schools find that even a small number of flagship school-authored units — tied to a national holiday or a core value the school emphasizes — is enough to give the program a distinct identity, without needing to replace the bulk of global-pack content.
