AT&T TKT II Practice Tests [2026]
The AT&T Technical Knowledge Test II, also called TKT II, is a challenging pre-employment knowledge test with 100 questions to complete in 1 hour and 40 minutes.
The test covers several categories, each containing a large number of topics, often presented in the same question. To ace the test, you need to master all of them and not rely on your strong suit.
The following guide will cover all the necessary information to succeed in the TKT II, with test topics, sample questions, and solving tips.

The Technical Knowledge Test II is a knowledge-based test that is part of the hiring process for technical jobs at AT&T. The test is designed to assess your knowledge of technical concepts required to perform certain technical positions in the company.
The test consists of 100 multiple-choice questions to answer in 1 hour and 40 minutes.
It covers five categories –
The Basic Electricity category of the Technical Knowledge Test includes more than 20 topics, including Alternative current (AC) and direct current (DC), Electrical transmission and waveforms, Electrostatic discharge, and identifying and using various electrical units, such as Voltage, Current, Resistance, and Power.
Identify the relay type shown below:
The correct answer is B.
SPDT is a single pole double throw relay. The schematic diagram of an SPDT is shown below.
There are three terminals:
When the relay is OFF, the COM terminal is connected with the NC terminal and when the relay is ON, the COM terminal is connected with the NO terminal. The schematic diagram of SPST (single pole single throw) and DPDT (double pole double throw) are also shown below.
The Basic computer knowledge category of the Technical Knowledge Test includes more than 10 topics, including Accessories/ System Tools, Control Panels, and Network Neighborhood/My Network Places.
Which one of the following is True for a buffer IC?
The Digital communication and transmission category of the Technical Knowledge Test includes the topics of advantages and disadvantages, Digital/Analog Conversion, Bit Frame, Bit Stream, T-carriers-hierarchy, overhead, framing, and data rates, and Units of measurement, including Binary Systems.
What is the binary value of the octal number 258?
Octal numbers have a base of eight numbers starting from 0 to 7. These numbers are represented with a subscript “8” after the number. Each hexadecimal number is represented by four binary bits. Since there are 2 octal numbers, the resultant binary of the given number will be 6 binary bits. Follow the figure provided below:
The Read and Interpret Technical Information category of the Technical Knowledge Test includes the topics of technical instructions, schematic diagrams, flowcharts, etc.
This is one of the most important test topics since this knowledge appears not only in this test section but also in nearly each and every OTHER section.
Although questions on the TKT-II test are multiple-choice, they will often combine knowledge of multiple domains, so memorization of separate data pieces is usually not a good strategy.
Instead, your preparation for the AT&T TKT-II test should aim to have a broad view of the topics and your test and be able to connect and integrate them.
What will happen if the forward button is pressed and released after a while
This question combines knowledge of print reading with troubleshooting and testing procedures. As a technical employee, you will need to use your knowledge to solve daily problems hands-on - so, such questions are going to be very common in the TKT-II test.
The Basic Math category of the Technical Knowledge Test includes the topics of addition, subtraction, multiplication, and division of positive and negative numbers.
While often overlooked by test-takers, this topic can be a major hurdle for those who have not touched the topic in a while and gets more candidates to fail than you may believe.
What is the value of X?
(15x)/9 = 2x + 4
TKT and TKT II are both technical knowledge tests administered by AT&T as pre-employment assessment tools, and both require specific knowledge relevant to technical jobs, but they differ in their lengths and structure.
