Pre-Qualification and Common Assessment Standard
Managing the pre-qualification process efficiently and encouraging the use of the Common Assessment Standard.This new approach was launched in 2019 by Build UK and the Civil Engineering Contractors Association following concerns that the proliferation of suppliers and duplication of effort and support associated with pre-qualification schemes. Through it’s introduction, the claim was that this approach will help the industry to £1bn by eradicating duplicate fees and inefficiencies.
What is pre-qualification and where does the Common Assessment Standard fit in?

What is Pre-Qualification and the Common Assessment Standard
Pre-qualification in construction refers to the process of evaluating and selecting qualified bidders before the bidding process begins. The process involves reviewing the qualifications of potential bidders, such as their financial stability, experience, skills, and resources, to determine whether they meet the minimum requirements to bid on a particular project. The process is based on companies completing and being audited against a Pre-qualification Questionnaire (PQQ).
The Common Assessment Standard is the industry-recognised standard for the pre-qualification of suppliers in the construction sector. It was developed to reduce the need for companies to hold multiple accreditations and is based on an industry agreed Standard Selection Questionnaire. FIS has recently joined the working group that monitors the question set to feed in the views of our members.
Response is audited and suppliers are certified to the Common Assessment Standard once a year by a Recognised Assessment Body, and this is accepted by a growing list of Contractors and Clients who should longer specify a particular assessment body. Over 22,000 companies now hold accreditation to the Common Assessment Standard.
Data Sharing
The growth of the Common Assessment Standard means clients should no longer be specifying particular PQQ providers. Companies that have been certified against the Common Assessment Standard by a Recognised Assessment Body can share their key PQ data with other Recognised Assessment Bodies to increase their visibility amongst more Contractors and Clients.
How do businesses get the Common Assessment Standard?
Certification is valid for one year from the date of issue, provided that any ‘time-critical’ documents are updated when they expire. There are already over 21,000 suppliers certified to the standard.

Recognised Assessment Bodies
Companies can choose either the desktop or the site-based level of certification based on what is most appropriate for their business. This will depend on a range of factors including trade, size and the requirements of the main contractors/clients that they work for.

Empowering the Responsible No
FIS is encouraging members to advertise their support for the Common Assessment Standard and adopt a Responsible No when they are confronted with behaviours and processes that undermine productivity, safety or responsible commercial practice. To this end we are encouraging members to use a Responsible No when asked to complete multiple PQQs. We accept that this is difficult in a commercial tender situation and time is often too tight, but we have prepared a short email that we suggest our members send to their client to help raise awareness of the efficiencies that the Common Assessment Standard brings. This email template is available here Common Assessment Standard Template Email.
Additional Support Available from FIS
FIS has recently joined the Common Assessment Standard Working Group to help review and develop the question set. To support this FIS also has a mirror group that is looking at how we support members in completing and mantaining their certified status. If you are struggling to complete the CAS or interpret guidance provided, contact the FIS team on 0121 707 0077 or email info@thefis.org.
