Thailand’s ฿4bn exam scandal deepens with nearly 6,000 disputed recruits still in office. CIB chief Pol Lt Gen Natthasak Chaowanasai says the probe will go beyond charged officials to pursue brokers, masterminds and those operating behind the scenes.
Thailand’s local government examination scandal is widening into a major political and criminal test for Prime Minister Anutin Charnvirakul. Nearly 6,000 candidates linked to irregular results remain in the civil service, despite evidence of altered examination papers and payments of up to ฿800,000 for passing scores. Police are now pursuing brokers, officials and figures operating behind the scenes, while investigators trace financial flows potentially worth ฿4 billion or more. The National Anti-Corruption Commission is examining 6,014 people, yet the opposition fears the full chain of responsibility may never emerge. Meanwhile, the Interior Ministry appears to have left the removal of affected appointees to individual local government bodies with differing regulations.
Thailand’s local government examination scandal continues to dog Prime Minister Anutin Charnvirakul’s government. Nearly 6,000 candidates linked to irregular examination results remain in the civil service.
The Interior Ministry has appeared to leave their removal to individual local government bodies. In parallel, police are widening their investigation into those behind the nationwide fraud.
The scandal centres on Thailand’s 2025 competitive examinations for local government positions. More than 400,000 people applied through the nationwide recruitment exercise. Investigators later uncovered evidence of systematic manipulation of examination results. Candidates reportedly paid between ฿350,000 and ฿800,000 to secure passing scores.
Thousands of altered exam papers widen probe as police pursue officials, brokers and masterminds
Notably, searches recovered thousands of examination papers linked to the investigation. Investigators found evidence that answers had been altered before results were processed. In July, officials found thousands of announced scores that did not correspond with examination papers. As a result, the investigation quickly expanded beyond candidates who received questionable scores.
The National Anti-Corruption Commission subsequently opened a special investigation covering 6,014 people. They included 22 state officials and 33 brokers or others connected with changing answers. Separately, investigators identified 5,959 candidates whose examination papers had been altered. The numbers turned the examination affair into a nationwide administrative and criminal investigation.
Yet thousands of affected candidates subsequently entered the local government system. The Interior Ministry moved towards revoking thousands of appointments in July. Despite that move, nearly 6,000 candidates connected with irregular results have not been removed. This week, the ministry appeared to place that responsibility with individual local government organisations.
Police, however, have signalled a broader approach to criminal responsibility. Investigators say their work will not end with government officials already identified. Instead, they are pursuing brokers, people behind the scenes and others connected with the operation. A clearer picture could emerge by late August or early September.
Police arrests and summonses widen as senior officials face scrutiny over local government exam fraud
Pol Lt Gen Natthasak Chaowanasai addressed the expanding investigation on Monday, August 17. The Central Investigation Bureau commander spoke at the Crime Suppression Bureau in Bangkok. His briefing took place at the Pracha Arak Building on Phaholyothin Road.
Significantly, Pol Lt Gen Natthasak rejected suggestions that the case had stopped after action against government officials. Police had already uncovered official involvement and issued summonses to people connected with the examination process. Among them was Ruangdej Sirikit of Srinakharinwirot University.
Mr Ruangdej is Director of the university’s Office of Educational and Psychological Testing. Investigators also identified Theerut Suphawibulphol, former Director-General of the Department of Local Administration. In addition, police targeted the group responsible for altering examination scores.
By July 15, three suspects had been arrested as investigators followed financial trails. Subsequently, another suspect was arrested as the inquiry widened. Police also summoned 11 people to acknowledge charges. Those actions, Pol Lt Gen Natthasak stressed, did not conclude the investigation.
Last week, the case was forwarded to the National Anti-Corruption Commission for further proceedings. As part of this, the commission appointed the Central Investigation Bureau to a special investigation committee. The commission also returned information to police for further work on several issues.
Police vow probe will now go beyond charged officials as financial trails point to billions of baht
That additional investigation is now underway. Pol Lt Gen Natthasak said police would act on information supplied by the anti-corruption commission. Investigators will compile their findings before submitting them back to the commission. He requested more time for officers to complete that work.
Clearer progress is expected by the end of August or early September. In response to concerns about the investigation’s scope, Pol Lt Gen Natthasak gave a firm assurance.
“I can confirm that it hasn’t stopped at just filing charges,” Pol Lt Gen Natthasak said.
He said responsibility would not end with officials already facing proceedings. “Now the entire matter is with the NACC, and the NACC is moving forward to take action against everyone involved.”
Crucially, he identified groups beyond those officials. They included “the brokers, those behind the scenes, and others connected.”
His comments address one of the central questions surrounding the scandal. Investigators have already identified officials, brokers and thousands of candidates with altered papers. On another front, they have examined financial flows potentially involving billions of baht.
Estimates reported during the investigation placed the operation’s potential value at approximately ฿4 billion or more. Individual candidates were reportedly charged between ฿350,000 and ฿800,000. Accordingly, investigators have followed financial trails alongside examination records and altered papers.
Political links come under scrutiny as opposition fears full extent of examination scandal may stay hidden
Attention has increasingly shifted towards the people who organised the operation. Questions have also arisen over whether responsibility extended beyond government officialdom. In particular, there have been calls to determine whether influential political figures had connections with the network.
No political figure has been publicly identified as a suspect in the supplied information. Prime Minister Anutin has nevertheless addressed the possibility of political involvement. He insisted politicians would receive no protection if evidence connected them with the scandal. He also said investigators should pursue the case regardless of who became implicated.
For its part, the opposition remains concerned that the complete extent of the operation may never emerge. Its concerns focus on whether investigators will reach everyone behind the nationwide scheme. Questions remain over those who organised, financed or protected the operation.
Against that backdrop, Pol Lt Gen Natthasak was questioned about possible links beyond government officials. He declined to disclose whether investigators currently possessed such evidence. Instead, he asked people to await a decision from the NACC’s main committee.
At the same time, he rejected suggestions that the investigation had been quieted. He said the case remained active and investigators were continuing their work. Moreover, everyone involved would be investigated according to the available facts and evidence.
Nearly 6,000 disputed appointments remain unresolved as investigators trace a suspected ฿4 billion scheme
Another unresolved issue concerns candidates who passed and were subsequently appointed. Pol Lt Gen Natthasak confirmed that several groups remain under investigation. Further action, however, must await information from the National Anti-Corruption Commission.
Consequently, thousands of appointments remain unresolved while the criminal investigation continues. Investigators identified 5,959 candidates whose examination papers had been altered. Nearly 6,000 candidates connected with irregular results have still not been removed from the civil service.
The figures show the extraordinary reach of the case. More than 400,000 people originally applied for positions through the local government recruitment exercise. Investigators then discovered thousands of questionable examination papers and discrepancies involving announced scores.
Further, the evidence pointed towards an organised payment system. Candidates reportedly paid hundreds of thousands of baht to secure passing results. The reported price started at ฿350,000 and reached ฿800,000 for individual candidates.
Investigators then turned towards financial transactions surrounding the operation. Those inquiries potentially involve billions of baht. Reported estimates have placed the overall value connected with the scheme at approximately ฿4 billion or more.
Altered exam papers lead investigators from candidates to senior officials, brokers and testing figures
Physical evidence has provided another major strand of the investigation. Police recovered thousands of examination papers during searches. Investigators then compared those papers with the results eventually announced. They found cases where answers appeared to have been changed before processing.
From there, the inquiry widened from candidates towards officials and brokers. Police examined people involved in administering and processing the examinations. They also pursued those suspected of directly changing examination scores.
The investigation eventually reached senior figures connected with local administration and examination testing. One was former Department of Local Administration chief Theerut Suphawibulphol. Another was Srinakharinwirot University testing director Ruangdej Sirikit.
More recently, the National Anti-Corruption Commission assumed a central role in the proceedings. The transfer has not ended the Central Investigation Bureau’s involvement. Rather, the commission has tasked police with additional investigative work on outstanding issues.
Once completed, those findings will return to the anti-corruption commission. Thus, the investigation remains active across both agencies. Police are simultaneously examining brokers and other people connected with the operation.
Interior Ministry leaves disputed appointments to local bodies as nationwide criminal investigation widens
The administrative fallout is unfolding separately across Thailand’s local government system. The Interior Ministry had previously moved towards revoking thousands of affected appointments. Even so, nearly 6,000 candidates linked with irregular results remain inside the system.
This week, responsibility for dealing with those appointments appeared to shift towards individual local government organisations. The national criminal investigation, meanwhile, continues to examine those behind the examination fraud.
Two major strands now run alongside each other. One concerns thousands of people appointed after irregular examination results. The second concerns the network responsible for producing those results.
Police have already reached government officials, brokers and candidates. Arrests have been made, while other suspects have received summonses. Beyond that, the NACC investigation encompasses 6,014 people connected with the affair.
Still, investigators have not publicly identified everyone suspected of operating behind the scenes. Pol Lt Gen Natthasak has confirmed that those inquiries remain active. He expects a clearer assessment of the case within weeks.
Political questions persist as police pursue brokers and figures behind the ฿4 billion examination scandal
The political questions therefore remain open. Mr Anutin has pledged that politicians will receive no protection if evidence implicates them. By contrast, opposition figures fear the full extent of the scandal may never become known.
So far, no political figure has been publicly identified as a suspect in the supplied material. Police have nevertheless confirmed that their investigation extends beyond officials already facing proceedings. Brokers and people behind the scenes remain targets.
Meanwhile, the financial investigation continues to carry substantial weight. Reported estimates place the potential value of the operation at approximately ฿4 billion or more. Investigators are tracing those financial flows alongside the examination evidence.
At the administrative level, the consequences are already substantial. Thousands of candidates entered local government after examination papers were identified as irregular. Yet responsibility for removing affected appointees now appears divided among local government bodies.
Government faces crisis on two fronts as disputed appointments remain and police pursue masterminds
The government therefore faces an unresolved problem on two fronts. Thousands of questionable appointments remain inside the local government system. At the same time, investigators have yet to publicly establish the complete chain behind the fraud.

Civil service chaos as 5,924 officials face the axe or change due to advised examination irregularities
For now, the Central Investigation Bureau is completing work requested by the anti-corruption commission. The NACC is considering the wider case and those connected with it. Police are also continuing their pursuit of brokers and others operating behind the scenes.
By late August or early September, Pol Lt Gen Natthasak expects clearer progress. Until then, nearly 6,000 disputed appointments remain unresolved. The nationwide investigation also remains open, with officials, brokers and masterminds still under scrutiny.
