NCIDQ IDFX PRACTICE TEST EXAM
2025 QUESTIONS AND ANSWERS
The five-step process outlined in William Pena's book, Problem Seeking, suggests that the first
step in gathering information about a client's needs is to establish goals. What is the suggested
order of the remaining four steps?
A. determine needs, collect and analyze facts, uncover and test concepts, state the problem
B. collect and analyze facts, determine needs, state the problem, uncover and test concepts
C. uncover and test concepts, state the problem, determine needs, collect and analyze facts
D. collect and analyze facts, uncover and test concepts, determine needs, state the problem -
ANS D.
The suggested order is establish goals, collect and analyze facts, uncover and test concepts,
determine needs and stat the problem. Establishing goals is a critical first step in the process
because it sets the direction for the other four steps.
According to William Penas book, Problem Solving, all design problems can be stated in terms
of form and which three other factors?
A.) Analysis, synthesis, and function
B.) function, economy, and time
C.) goals, facts, and function
D.) economy, time, and synthesis - ANS B.
Design problems can be stated in terms of form, function, economy, and time. Can be broken
down further ex: economy can be studied in terms of initial cost, operating cost, and life-cycle
cost.

,Which of these types of information regarding a new multipurpose room in an assisted-living
facility would be the LEAST important for the interior designer to give to the mechanical
engineer?
A.) the ages of the residents in the facility
B.) the types of activities the room will be used for
C.) the maximum number of residents using the room at one time
D.) a copy of the reflected ceiling plan - ANS A.
Options B and C relate directly to how much heat will be generated and how much ventilation
will be needed in the room, both of which the mechanical engineer must design for. The
reflected ceiling plan will indicate the room's ceiling type and its lighting design, which the
engineer can use to estimate how much heat will be generated by the lights. As long as the
engineer knows the facilities occupancy type, occupant age is of little concern.
Apart from being decorative, the primary advantage of using tapestries in Gothic and
Renaissance castles was that they
A. reduced sound reflection
B. minimized drafts
C. raised mean radiant temperatures
D. reduced condensation on walls - ANS C. Tapestries served all 4 but their advantage was
that they decreased heat loss through radiation by covering stone walls with an insulating
material. This, in effect, raised mean radiant temperatures
Interior Spaces often need to be multifunctional or flexible. What are the three components of
flexibility as a programmatic design concept?
A. versatility, convertibility, and grouping
B. expandability, hierarchy, and flow
C. flow, hierarchy, and convertibility
D. convertibility, expandability, and versatility - ANS D.
convertibility, expandability, and versatility.
CONVERTIBILITY- space's usefulness for different functions through the conversion of the space.

, EXPANDABILITY refers to a space's ability to accommodate growth through expansion.
VERSATILITY- a space's ability to accommodate a variety of activities.
An inter-designer is researching ergonomic chairs for an office. Which of the following design
criteria is LEASTimportant to consider?
A. DURABILITY
B. Lumbar support
C. HEIGHT ADJUSTMENT
D. FOAM CONSTRUCTION - ANS A.
WHILE DURABILITY IS A DESIRABLE CHARACTERISTICS IN AN OFFICE CHAIR, IT IS MORE
IMPORTANT THAT THE CHAIRS DESIGNED THE ERGONOMICALLY CORRECT. LUMBAR LOWER
BACK SUPPORT, HEIGHT ADJUSTMENT, AND FUNK INSTRUCTION ARE THREE IMPORTANT
CHARACTERISTICS OF ERGONOMIC DESIGN.
Which of the following statements regarding programming interviews is generally false?
A. They can establish the accuracy of questionnaires
B. They minimize in accurate results from ambiguous questions
C. They allow for the road regulation of information that the programmer may not have
considered
D. They make efficient use of the interviewers time - ANS D.
Because programming interviews consumes so much time and often require two people to
conduct, and because interviewees tend to talk more than is necessary, interviewing is often
and inefficient, although valuable, way to verify information.
An interior designer has been hired to re-designed a large Victorian house into a bed and
breakfast in. During an initial interview, the client says that he wants to restore the interior to
an authentic Victorian look, as well as in large some of the bedrooms into suites so that the N
will be the best in town. After hearing these comments, what should be the designers first
course of action?
A.) Suggest the client also retain an architect to determine the feasibility of enlarging rooms
and removing walls
