How the TOJ 377 works

Since 22 July 2025, everyone who needs a supervised Test of Judgement result takes the TOJ 377. It is supervised and taken in person at a federal government building, on the PSC’s Candidate Assessment Tool. You book the session with the Reservation Code in your invitation.

The items work like the unsupervised TOJ 376: a situation, one possible response and the question “How effective is this response?”, answered on six points from Very ineffective to Very effective. The difference is pace: 40 items in 60 minutes is 1 minute 30 seconds each, against 1 minute 44 seconds on the TOJ 376.

A department can use it in two ways. In a two-step process it is step 2, open only to those who passed the TOJ 376, and you must pass both. Or it can be the only judgement test. A TOJ 377 result cannot replace a TOJ 376 result, or the other way round, and an existing TOJ 377 score does not let you skip step 1.

Your result is a level from J-01 to J-10 against earlier test takers, ready in My Tests 48 hours after the test. J-10 is the 50th percentile or higher, and each department sets its pass mark between J-02 and J-07.

How to rate under tighter timing

The judging is the same as on the TOJ 376; the routine needs to be quicker:

  • Read the situation once and name the real problem in a few words before you read the response.
  • Then ask one question of the response: does it make things worse, do nothing, possibly help, help, or solve the problem? That maps straight onto the six points.
  • When the same situation returns with another response, rate it fresh. Do not rank it against the one you saw before.
  • If you are torn between two neighbouring points, pick one and move on. Some answers earn partial marks, so a near miss still scores.

Worked example

Situation: you lead a small project. In a meeting, two team members disagree about which of two approaches to take, the discussion is running well over time, and a decision is due by the end of the week.

Response: ask each of them to send you a one-page summary of their approach by the end of the day, then decide, and explain your reasons to both. This settles the question in time, hears both sides and keeps the team informed, so it rates Effective or Very effective.

The same situation with a different response: choose the approach of the more senior team member to end the meeting quickly. It ends the delay but ignores the merits of either approach and may leave the other person disengaged, so it sits on the ineffective side of the scale.

Tips for the real TOJ 377

  • If you have just passed the TOJ 376, the format will be familiar. Practise working faster rather than learning something new.
  • Book early with your Reservation Code, arrive in good time and allow 20 to 30 minutes for administration.
  • Watch the timer in the bottom-left corner. At 1 minute 30 seconds an item, a few long hesitations add up quickly.
  • Rate every item before time runs out. There is no penalty for guessing.
  • The test is bilingual. You can switch between English and French at any time if a situation reads more clearly in the other language.
  • The retest wait is 180 days.

Practise the TOJ 377 on CogniPrep

Our TOJ 377 has 40 items in 60 minutes on the same six-point scale, with free movement and Mark for Review. We key each response to one rating, give full credit for it and 20 points less for each step away, because the PSC does not publish its formula. Your result is placed on the J-01 to J-10 scale against other CogniPrep users, not the PSC’s norm group. It draws on the same situations as our TOJ 376, so a situation can come back with a different response if you play both.

Questions candidates ask

How many questions are on the TOJ 377?

40, in 60 minutes, each a situation and one response to rate from Very ineffective to Very effective.

What is the difference between the TOJ 376 and TOJ 377?

The TOJ 376 is 52 items in 90 minutes at home. The TOJ 377 is 40 items in 60 minutes, supervised in person. One result cannot replace the other.

Do I have to pass the TOJ 376 before the TOJ 377?

In a two-step process, yes: only those who pass the TOJ 376 are eligible, and you must pass both. Some processes use the TOJ 377 alone.

What is the pass mark for the TOJ 377?

Each department sets its own, between J-02 and J-07 on the J-01 to J-10 scale.
