14 of the 16 certificates, in one app
Tell the app which certificates you hold and it hides everything else — you revise your units, not somebody else's. Not covered yet: O7, S6.
Required by everyone
1 certificateHeld by operatives and supervisors alike. If this certificate expires, every other street-works certificate you hold is invalid.
Operative units

Signing, Lighting & Guarding
Setting out a works site so traffic and pedestrians stay safe: the survey and risk assessment before you start, safety zones and layout, provision for pedestrians and vulnerable users, and the forms of traffic control.

What you get
Timed mock for each certificate
20 questions in 45 minutes, marked against the 16/20 pass mark — the format the real theory test uses.
Every answer explained and sourced
Each explanation says why the key is right, why each distractor is wrong, and names the clause or paragraph it comes from — so you can look it up yourself.
Look-up drills
140 drills that train the skill the open-book units actually test: finding the right page fast, under time pressure.
Common questions
What is the NRSWA theory test?
Each street works unit is assessed by a theory test of 20 multiple-choice questions in 45 minutes, with 16 out of 20 needed to pass, alongside a practical assessment where the unit requires one. Confirm the current format with your assessment centre before you sit it.
Which certificates do I need?
Everyone needs LA. Operatives then take the O units for the work they do, and supervisors the S units. O1 is a key certificate for every other O unit, and S1 for every other S unit — if a key certificate expires, the units that depend on it stop being valid.
Does this app award a street works card?
No. It is revision material only. Cards are issued by the registered assessment bodies after you pass their assessments; nothing here is a qualification, an assessment or an endorsement.
Does it cover Scotland, Wales or Northern Ireland?
Not yet — the question bank is written for England. Reinstatement specifications and some duties differ elsewhere in the UK, so questions written for England would be misleading if applied to another nation.
Revise on the van, on site, anywhere
