What Does "1A DSDC Accredited" Actually Mean?

A dementia-care professional opened a live chat on this site and typed: "i see you are 1A DSDC Accredited. What does that mean?" It is the right question, it went unanswered for far too long, and the honest answer is more useful than the badge. Everything below is taken from the Dementia Services Development Centre's own published documents -- its Product Accreditation information and guidance booklet (November 2021) and its Product Accreditation Directory (July 2023) -- both downloaded from dementia.stir.ac.uk on 16 October 2026. Where we cannot evidence something about our own certificate, this article says so instead of filling the gap.

What a DSDC product accreditation is#

The Dementia Services Development Centre (DSDC) is based at the University of Stirling. Its guidance states that its product review and accreditation service was launched in 2017, that a manufacturer submits a product for assessment, and that each assessment is carried out by a minimum of two DSDC specialists -- its examples are architects, designers, registered nurses and researchers. Where possible DSDC asks for a 1:1 sample; where that is not possible it can review a product in design development, or review 2D or 3D production information. The assessment is built around a benchmark specification written for that product, plus a desktop review of recent research and of comparable products on the market.

DSDC states that to achieve a product accreditation rating, products must meet ten product design principles. Those principles are DSDC's criteria for assessing a product, not claims about any particular product, and DSDC notes that not all of them are relevant to every product. DSDC records them as informed by published research in the field (Bowes et al, 2019; Fleming et al, 2008).

What the rating describes -- and what it does not#

This is the part the badge hides. A DSDC rating is not a score out of ten. DSDC's guidance says the suitability of the product "is classified by a number with corresponding explanation of use, within a ratings key" -- so the rating is a statement about where a product can be used. The only ratings key DSDC publishes in that booklet is an example for flooring, and it runs Class 1a, Class 1b, Class 2 and Not suitable: the top class describes products that can be used without restriction, the middle classes carry cautions about where they are appropriate, and the bottom one says the product should not be used in areas used by people with dementia. DSDC says the key varies with the product, so the wording written for a floor is not the wording written for a sign.

An accreditation belongs to a product, not to a company#

This is the single most useful thing to take away. DSDC's guidance states that the Accredited Product logo "is awarded on the merit of the individual product and where applicable, colour-way", and that "the accreditation of the product does not merit the final application, the product performance or its interface with other products or finishes". Read plainly: a sign assessed on its own merits can still be hung in the wrong place, or on a wall it does not contrast with, and the accreditation says nothing about that. It also means a company-wide badge is not evidence. The certificate is, because the certificate names a product.

What DSDC's directory records about our own signs#

DSDC publishes an Accredited Products Directory listing, in its own words, "all the companies which have had products assessed and have received an accreditation rating to date". In the July 2023 edition -- the edition linked from DSDC's product accreditation page when we checked on 16 October 2026 -- the Signage section lists one company: Wayfinders, who manufacture Signage for Care. The entry reads "2018 - Toilet sign: Garnet Red; Heather Purple; Carolina Blue; Veridian Green; Sage Brown; Oak; White Pine; Walnut".

That is what the public directory records, and it is checkable: the directory is a free download from dementia.stir.ac.uk. It is not the same thing as the scope of a certificate, and we are not going to describe a scope or a renewal date we have not put in front of you. If the scope matters to your specification -- and in a tender it does -- ask us for the certificate, and ask DSDC to confirm it. Both are reasonable, and a supplier who minds being asked has told you something.

What it does not mean#

A product accreditation is an assessment of a product's design against DSDC's principles. It is not a clinical finding, and it is not a statement about what will happen to the people living in your building. Our signs are made to help somebody find a room; that is the claim we make for them, and it is the only one a sign can carry. Anybody selling you signage on a stronger promise than that is selling you something a sign cannot do.

So: "1A DSDC accredited" means a named product was assessed by DSDC specialists against ten published design principles and classified for suitability of use. It is a real and relatively rare thing in this market. It is also a document, and a document is worth more to you than a logo. Ask for it.
