USPS Application Process

The USPS application process differs depending on the job position and the level of expertise needed for fulfilling the job requirements. 

  • The first step towards your USPS career is searching for open job positions by geographical location on the USPS career website
  • Then, you need to create a profile through their eCarrers System, where all your progress will be saved and available for USPS representatives during the hiring process. This is where you also need to submit your resume, skillset, educational background, and previous employment.
  • This USPS profile can later be used to apply for numerous job positions if you don’t get hired for the position you initially applied for. 
  • In the third part of the employment process, depending on the job position you apply for, you might take non-proctored assessments, proctored assessments, or both. You can do non-proctored assessments online from your home.
  • Assigning Proctored assessments is conducted in an accredited testing center. Either way, you will receive an email from USPS explaining the following steps and guiding you to their assessments. 
  • For some positions, this is the end of the application, and applicants just need to wait to be contacted by USPS for further details. Highly demanding and specialized job positions have one more step: the Panel Interview or alternatively called, the Oral Test.
  • You will meet with three USPS representatives and be asked questions of technical nature (similar to the proctored assessments you previously took) and about your work ethic and communication skills when working in teams. In this segment, a representative will also ask you for safety procedures and protocols (LOCKOUT/TAGOUT.)
  • The last step is drug screening. With a rigorous drug use and abuse policy, the USPS conducts thorough 5-step drug screening. Even highly competent candidates applying for a USPS role might be rejected due to failing the drug test. 

Requirements for Joining the USPS

  • Must be 18 years of age at the appointment or 16 years old with at least a high school education.
  • Must pass a criminal background check (Inspection Service criminal check), a narcotic test, and additional healthcare examinations, as needed.
  • The candidate for a job should be a U.S. citizen, a U.S. naturalized permanent resident, an American Samoan, or a resident of some other U.S. region.
  • The job applicants must provide their recent job portfolio.
  • Job apprentices must be registered with Selective Service if appropriate.

The Inspection Service Criminal Background Check

The United States informational materials are used to perform the Inspection Service’s crime history test. An investigation into an applicant’s prior criminal record entails looking back five years to see where they lived, worked, or attended school in the United States. 

If the person has not spent their last five years in the U.S., officials cannot conduct a criminal background check and will disqualify the individual for further proceeding in the USPS employment process.

What Is the USPS 955 Postal Exam?

The Postal Exam 955 is designed specifically for those seeking employment within technical roles at the USPS.

Individuals wanting to apply for multiple USPS job roles, like Servicing Repairer, Digital Specialist, Building Equipment Technician, and many others, are screened using the Postal Exam 955, also known as the USPS Maintenance Exam.

The test lasts for 75 minutes and includes eight topics in total. It is a proctored, computer-based exam that is taken in testing facilities.

The Ramsay Test, also known as the MultiCraftTest, is the foundation for the exam’s composition and structure. The 955 test is a newer, updated, and summed version of his predecessors – the 931, 932, and 933 tests. 

The USPS 955 exam is taken by only competent and already experienced professionals with backgrounds in engineering, equipment mechanics, electronic technicians, and the like. This makes the USPS Postal 955 exam extremely extensive and complex for anyone else. 

The reason for its more complex nature compared with other postal exams is that any candidate hired will be responsible for all of USPS’s equipment maintenance. Thus, the company must only hire the most competent candidates. To move forward in the hiring process, it is essential to finish the USPS 955 with a very good score.

The most efficient way to prepare for this pre-employment exam is by utilizing online test practice materials and exams with detailed explanations. The more familiar you are with the exam structure, the more confident you will feel when taking the test.

There are two categories of questions on the test: multicraft and spatial reasoning.

The employment application via USPS 955 exam is free. If you see websites charging a fee, it means they are not honest. The best practice is to report them to the United States Postal Inspection Service.

For your best experience, use a PC or laptop instead of a mobile device. Ensure you use widely-used web browsers like Mozilla Firefox, Chrome, or Opera. Also, ensure Adobe PDF Reader is installed and allowed on your browser.

You also must have a valid email account to apply for a job or create your applicant’s profile. It is the medium that USPS takes to speak with you regarding your application and job positions, and status.
