How we score disability services and support organisations in Perth

This guide covers 121 disability services and support organisations in Perth, and every one of them gets scored the same way, using the same public rubric. There is no manual ranking and no "editor's pick" pushed to the top because we like a business more than the numbers say we should. The score is built from five measured signals, and we explain each one below so you can judge for yourself whether it reflects what matters to you.

The five signals, heaviest first

Each business gets a composite score from 0 to 100, made up of:

• Sentiment (28%): a synthesis of what recent reviews actually describe, praise as well as complaints.
• Rating (26%): the aggregate Google star rating.
• Volume (20%): how many reviews exist, log-scaled so 400 reviews does not simply dwarf 40, but still counts for more than 4.
• Recency (12%): how recently people have actually left reviews.
• Completeness (14%): whether phone number, website, hours and address are all listed and accurate.

Why sentiment carries the most weight

Two support providers can carry the identical 4.3-star average and still be very different businesses to deal with. One might have a handful of old complaints about a single roster mix-up, while the other has a recurring pattern in its recent reviews about missed shifts, poor communication with participants' families, or plan managers who are hard to reach. A star average cannot show you that difference. It compresses everything into one number and throws away the detail.

Reading what people actually wrote is the only way to catch that pattern. That is why sentiment, our synthesis of recent review themes, is weighted higher than the star rating itself. For a disability support choice, where consistency of care and communication genuinely affects someone's daily life, this distinction matters more than it might for a one-off purchase.

Why the other signals matter

Rating still counts for a lot (26%), because it reflects the broad, aggregated judgement of everyone who has left a review, and it is the number most people check first. Volume (20%) matters because a business with 5 reviews and a business with 300 are not equally proven quantities: log-scaling means extra reviews still help a business's score, just with diminishing returns rather than an unfair multiplier. Recency (12%) matters because a support organisation that was excellent three years ago under different management or staff may not be the same organisation today. Completeness (14%) is the practical layer: a provider whose phone, hours, website and address are all correct and listed is simply easier and safer to contact, which matters when you are trying to line up support quickly.

The honest limits

We are upfront about where this method is weaker. A business with only a few recent reviews cannot support a confident score, no matter how positive those reviews are, so it gets labelled as a low-confidence score rather than presented as equivalent to a business with a deep, recent review history. We synthesise review themes rather than republishing full text, and we always link out to Google so you can read the original source yourself and form your own view.

Scores are earned strictly from this rubric and the underlying data. They are never hand-edited. Where paid placement exists anywhere on this site, it is always labelled clearly and it never changes a score. If any list on this site has picks or ordering that were editor-reviewed rather than purely rubric-driven, that will be disclosed openly on that page, such as our best NDIS plan management providers in Perth list.
