Civil Service Exams Toxicology Technicians 2026: changes in the call you must review

Key data

If you are applying for the civil service exams for Specialist Technicians of the National Institute of Toxicology and Forensic Sciences, there is a change you need to know about right now. The Order PJC/390/2026, of April 17, modifies the original call published in December 2025 (Order PJC/1535/2025). This means that part of what you read when you registered may have changed.

This type of modification in already-announced selection processes is not exceptional, but it can have direct consequences for those in the middle of preparation: an updated syllabus, a corrected requirement, or a shifted date can completely change your planning.

What does this regulation establish?

The Order PJC/390/2026 formally modifies the call for the selection process for admission, through the general system of open access, to the Special Body of Specialist Technicians of the National Institute of Toxicology and Forensic Sciences.

The original call was approved by Order PJC/1535/2025, of December 12, 2025. The modification occurs approximately four months after its initial publication.

According to available information, the changes may affect one or more of the following elements of the selection process:

• Participation or admission requirements
• Syllabi or content of the tests
• Dates of the process or exam calendar
• Organizational conditions of the selection process

This type of modification typically responds to corrections of errors detected after initial publication, subsequent regulatory updates, or necessary organizational adjustments. The full text of the specific changes is available in the official BOE source.

Economic and operational impact

For registered candidates, the impact is not economic in the strict sense, but it does have a real cost in terms of time and planning. Preparing for civil service exams with an outdated syllabus or outdated bases poses a direct risk: studying content that is no longer valid or being unaware of a modified requirement can compromise months of work.

From an operational perspective, the most relevant effects are:

• Risk of exclusion if any admission requirement has changed and the candidate has not verified it.
• Mismatch in preparation if the syllabus or tests have been modified.
• Calendar change if the dates of the process have been shifted, which directly affects study planning.

For preparation academies and private tutors, this modification also implies updating materials and communicating changes to their students as quickly as possible.

Who does it affect?

• Candidates registered in the selection process for the Special Body of Specialist Technicians of the National Institute of Toxicology and Forensic Sciences.
• Applicants who are considering registering if the deadline is still open or if a new period opens.
• Academies and tutors offering training for this selection process.
• Professionals in the field of state forensic and toxicology laboratories who follow the evolution of public employment calls in their sector.

Practical example

Imagine you have been preparing for three months for the civil service exams for the Special Body of Specialist Technicians of the National Institute of Toxicology based on the syllabus published in December 2025 with the original call (Order PJC/1535/2025).

Order PJC/390/2026 enters into force on April 17, 2026 and modifies that call. If you do not review the content of the modification, you could be studying topics that are no longer part of the program, ignoring a new qualification requirement, or being unaware that the exam has been moved forward or delayed.

The immediate step is to access the full text of Order PJC/390/2026 in the BOE, identify exactly which articles or annexes of the original call have been modified, and update your planning accordingly.

What should candidates do now?

1. Access the BOE and read the full text of Order PJC/390/2026 to identify exactly what has changed compared to the original call from December 2025.
2. Compare with Order PJC/1535/2025 to detect which articles, annexes, or conditions have been modified, corrected, or eliminated.
3. Verify that you still meet the admission requirements after the modification, especially if it affects qualifications, registration deadlines, or required documentation.
4. Update your study syllabus if the modification has affected the content of the tests or the structure of the selection process.
5. Consult with the academy or tutor if you are receiving external training, to ensure that the materials are already updated with the changes from April 2026.
6. Save the text of the modification along with the original call as reference documentation throughout the process.
